Description

Technical Field

[0001] The invention relates to a beam control device and a communication perception integrated system. Background Art

[0002] The polarization direction of the antenna refers to the vibration direction of the radio wave. Generally, the antenna includes two orthogonal polarization directions, such as horizontal polarization and vertical polarization, or 45° polarization and 135° polarization. Among them, horizontal polarization means that when the communication system or sensor system transmits a signal, the vibration direction of its radio wave is horizontal. Vertical polarization means that when the communication system or sensor system transmits a signal, the vibration direction of its radio wave is vertical. 45° polarization means that when the communication system or sensor system transmits a signal, the vibration direction of its radio wave is 45°. 135° polarization means that when the communication system or sensor system transmits a signal, the vibration direction of its radio wave is 135°. Because horizontal polarization and vertical polarization (or 45° polarization and 135° polarization) are 90° orthogonal and do not interfere with each other, for the communication system, different polarizations form independent wireless channels, and the system capacity is doubled. When the electromagnetic waves emitted by the sensing system hit the target object, the characteristics of the target object itself will change the polarization state of the reflected electromagnetic waves. This phenomenon is called the "polarization change effect". By measuring the change in this polarization state, the physical properties of the target object, such as shape, structure and material, can be inferred, which can be applied to weather radars that detect clouds and rain.

[0003] However, for the Integrated Sensing and Communication (ISAC) system for detecting aerial targets, the two polarization directions of the transceiver system do not achieve the corresponding target object recognition resolution gain. If the target object recognition resolution needs to be improved, the number of transmitting or receiving antennas needs to be increased, which increases the cost. Summary of the invention

[0004] The purpose of the present invention is to provide a beam control device and a communication perception integrated system, which can support the perception function of ISAC on a communication system platform with low cost and high angular resolution.

[0005] The present invention discloses a beam control device, comprising: a plurality of first antenna port groups and at least one second antenna port group, wherein the first antenna port group is used to connect a first polarized antenna group, and the second antenna port group is used to connect a second polarized antenna group, and each antenna group includes one or more antennas with the same polarization direction; a plurality of first beam channel groups and at least one second beam channel group, wherein the first beam channel group is connected to the first antenna port group, and the second beam channel group is connected to the second antenna port group; a first signal terminal and a second signal terminal, wherein the first signal terminal is used to connect to a first radio frequency terminal, and the second signal terminal is used to connect to a second radio frequency terminal; When the switching switch is configured to: select the first signal end to multiple first antenna port groups, and select the second signal end to at least one second antenna port group, at this time, the first RF end is selected to multiple first polarized antenna groups, and the second RF end is selected to at least one second polarized antenna group. The first polarized antenna group can be used to transmit a first polarized signal, and the second polarized antenna group can be used to transmit a second polarized signal, that is, the communication signal from different first RF ends and second RF ends, each polarized antenna generates a polarized beam, so that the two groups of polarized antennas form two beams, and the two beams are orthogonal and do not interfere with each other, so the two beams can carry different information and improve the communication capacity; at this time, the centers of the two groups of polarized antennas form a virtual aperture; When the switching switch is configured to: select the first signal end to a part of the first antenna port groups, and select the second signal end to another part of the first antenna port groups, at this time, the first RF end is selected to a part of the first polarized antenna groups, and the second RF end is selected to another part of the first polarized antenna groups. All the sensing signals are of the first polarization, that is, the sensing signals from different first RF ends and second RF ends can make a part of the first polarized antenna group form a beam, and another part of the first polarized antenna group form another beam; because one part and another part of the first polarized antenna group are separated in space, the center of one part of the first polarized antenna group forms a virtual aperture, and the center of the other part forms another virtual aperture, so that the virtual aperture is doubled, the angular resolution of the target object is improved, and the number of antennas does not need to be increased, reducing costs.

[0006] In this solution, the perception function and the communication function reuse the antenna group. By configuring the state of the switching switch, the virtual aperture of the antenna group can be flexibly configured to meet the communication capacity of the communication function and the angular resolution of the perception function without increasing the number of antennas.

[0007] In one embodiment, the switch includes a first switch and a second switch, and in another embodiment, the switch includes a first switch to a fourth switch. In this solution, two switches can support the ISAC's sensing function at a low cost, and four switches can time-division multiplex antennas in two polarization directions, so that it can also be applied to weather radars.

[0008] The present invention also discloses a communication perception integrated system, comprising a beam control device and an antenna array; the beam control device is used to beamform a service signal; the antenna array comprises a transmitting antenna array and a receiving antenna array, and the transmitting antenna array is used to receive the service signal after beamforming. In one embodiment, the transmitting antenna array is arranged on both sides of the receiving antenna array in a first direction. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0010] In order to make the purpose and technical solution of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0011] In this solution, "enabling" refers to connecting a signal or circuit to a specific path or device. For example, enabling the first RF terminal to multiple first polarized antenna groups can be understood as that the first RF terminal is connected to multiple first polarized antenna groups by the switch setting.

[0012] First, the application scenario of the present invention is described.

[0013] ISAC can unify the design of communication and perception functions. The communication service is used to transmit data between users, such as voice data, and the perception service is used for radar positioning. This enables the wireless network to achieve high-precision and refined perception functions while performing high-quality communication interactions, thereby improving the overall network performance and service capabilities.

[0014] Whether it is a sensing service or a communication service, multiple antennas are required to transmit and / or receive signals, wherein the signals on the multiple antennas can be coherently combined so that the multiple antennas can transmit directional electromagnetic wave energy or receive directional electromagnetic wave energy. The method of combining the signals on the multiple antennas can be called beamforming, which forms an enhanced signal in the desired direction and suppresses the signal in other directions by adjusting the amplitude and / or phase of the multiple antennas. The directional electromagnetic wave energy transmitted or received by multiple antennas can be called a beam.

[0015] Figure 1 The hardware architecture block diagram of the ISAC system is shown.

[0016] like Figure 1 As shown, the ISAC system includes a signal transmitter 210 and a signal receiver 220 .

[0017] The signal transmitter 210 includes: a channel encoder 212, which is used to receive a signal stream and encode the signal to increase the anti-interference ability and error correction ability, wherein the signal stream includes a communication stream and a perception reference, and the perception reference is used as a reference signal for positioning. A modulator 213 receives the signal encoded by the channel encoder 212 and is used to modulate the signal, including amplitude modulation, frequency modulation, etc.; a precoder 214 receives the signal modulated by the modulator 213 and is used to precode the signal before sending it to optimize the transmission quality, efficiency and anti-interference ability of the signal; a D / A converter 215 receives the digital signal precoded by the precoder 214 and is used to convert the digital signal into an analog signal for subsequent processing; a radio frequency front end 216 receives the analog signal output by the D / A converter 215 and is used to amplify, filter, mix, combine, split, phase shift or One or more of the processes such as beamforming; antenna 211 is used to transmit communication and perception signals, that is, to transmit the signal processed by the RF front end 216; wherein, the transmitted communication signal and the perception signal can be sent in time-sharing. In the communication stage, the signal stream passes through the channel encoder 212, the modulator 213, the precoder 214, the D / A converter 215, and the RF front end 216 in sequence, and then the communication signal is transmitted by the antenna 211; in the perception stage, the perception reference passes through the channel encoder 212, the modulator 213, the precoder 214, the D / A converter 215, and the RF front end 216, and then the perception signal is transmitted by the antenna 211.

[0018] The signal receiver 220 includes: an antenna 221, used to receive communication signals and perception signals; a radio frequency front end 222, used to amplify, filter, combine, split, phase shift or beamform the signal received by the antenna 221. In this embodiment, in the communication stage, the radio frequency front end 222 is used to amplify, filter, combine, split, phase shift or beamform the received communication signal. One or more processes; in the perception stage, the radio frequency front end 222 is also used to perform sum and difference calculations on the received perception signals to facilitate the positioning of the device to be detected.

[0019] The signal receiver 220 also includes: an A / D converter 223, which receives the analog signal processed by the RF front end 222 and is used to convert the received analog signal into a digital signal, wherein the analog signal may include an analog communication signal and an analog perception signal; a clock frequency offset 224, which receives the digital signal output by the A / D converter 223 and is used to correct the frequency offset of the received signal to ensure signal synchronization; a channel estimation 225, which receives the signal corrected by the clock frequency offset 224 during the communication phase and is used to estimate the channel characteristics for signal recovery and decoding; a MIMO equalizer 226, which receives the signal processed by the channel estimation 225 during the communication phase, Used to equalize signals in a multiple-input multiple-output (MIMO) system to reduce interference and multipath effects; demodulation 227, receiving the signal processed by the MIMO equalizer 226 in the communication stage, used to restore the received modulated signal to the original digital signal, restore the original communication stream, and transmit the communication information; matched filter 228, receiving the signal corrected by the clock frequency offset 224 in the perception stage, filtering the signal to improve the sensitivity and accuracy of signal detection; moving target detector 229, receiving the signal filtered by the matched filter 228 in the perception stage, used to detect the existence and position of the moving target based on the signal; CFAR The detector 230 receives the signal transmitted by the moving target detector 229 in the perception stage, and is used to detect the target object in the noise background; the DoA estimator 231 receives the signal input by the CFAR detector 230 in the perception stage and estimates the direction of arrival of the signal; the clustering 232 receives the signal input by the DoA estimator 231 in the perception stage, and is used to perform cluster analysis on the detected target objects to identify and classify different target objects; the object detection 233 receives the signal input by the clustering 232 in the perception stage, and is used to detect and identify the target object; the target tracking 234 receives the signal input by the object detection 233 in the perception stage, and is used to track the motion trajectory of the target object.

[0020] In the ISAC system, the precoder 214, modulator 213, channel encoder 212, channel estimation 225, MIMO equalizer 226, and demodulation 227 are used for communication functions to parse information such as voice data carried in communication signals (or communication streams); matched filter 228, moving target detector 229, CFAR detector 230, DoA estimator 231, clustering 232, object detection 233, and target tracking 234 are used for perception functions to obtain positioning information or trajectory information of the device to be detected from the perception signal (or communication reference). Antenna 211, RF front end 216, antenna 221, RF front end 222, and clock frequency offset 224 are all used when the system performs perception functions and communication functions, so they can be reused. For example, if the perception function and communication function are performed in time-sharing (described in detail below), antenna 211, RF front end 216, antenna 221, RF front end 222, and clock frequency offset 224 are reused in different working periods. In some embodiments, the antenna of the signal transmitter 210 can be time-division multiplexed with the antenna of the signal receiver 220, and the radio frequency front end of the signal transmitter 210 can be time-division multiplexed with the radio frequency front end of the signal receiver 220.

[0021] In some technologies, in order to achieve multiplexing of the above hardware structure, the communication signal and the perception signal are transmitted (including transmission and / or reception) in a time-sharing manner.

[0022] Figure 2 It is a schematic diagram of the frame structure of time-sharing transmission of communication signals and perception signals.

[0023] like Figure 2 As shown, the horizontal axis is the time domain and the vertical axis is the frequency domain. The communication signal and the perception signal occupy different symbol resource bits in the time domain and the frequency domain, forming an ISAC frame structure. Each unit in the time domain can be called an orthogonal frequency division multiplexing (OFDM) symbol, and each unit in the frequency domain can be called a subcarrier. There is a cyclic prefix (CP) between different symbols to reduce interference between symbols. Among them, the symbol is used to transmit the communication signal or the perception signal, and the CP does not transmit the communication signal or the perception signal.

[0024] Figure 3 It is a partial structural diagram of the communication system.

[0025] like Figure 3 As shown, the communication system includes a radio frequency end 101, a beam control device 102 and an antenna array 103.

[0026] The radio frequency end 101 includes a first radio frequency end 1011a and a second radio frequency end 1011b, and the first radio frequency end 1011a and the second radio frequency end 1011b are used to realize the conversion between the baseband signal (digital signal or intermediate frequency signal) and the radio frequency signal, and provide or receive two service signals to the beam control device 102. As an example, the service signal includes a communication signal and a perception signal. The communication signal and the perception signal are sent in time division, and the communication signal carries information data, such as voice data, etc. The perception signal has a waveform feature for detection, and the perception signal does not include information data. The first radio frequency end 1011a and the second radio frequency end 1011b are two independent radio frequency ends, for example: the first radio frequency end 1011a can be a V end, and the second radio frequency end 1011b can be an H end; or, the first radio frequency end 1011a can be an H end, and the second radio frequency end 1011b can be a V end. In the communication stage, the H end is used to send a signal of one polarization, and the V end is used to send a signal of another polarization.

[0027] The beam control device 102 includes multiple antenna port groups, multiple beam channel groups, a first signal terminal and a second signal terminal. The first signal terminal 105a is used to connect to the first radio frequency terminal 1011a, and the second signal terminal 105b is used to connect to the second radio frequency terminal 1011b to receive service signals from the first radio frequency terminal 1011a and the second radio frequency terminal 1011b. The multiple beam channel groups are used to adjust the phase and / or amplitude of the service signal to perform beamforming. As an example, Figure 3 Only four beam channel groups 1021a-1021d are shown, and each beam channel group 1021a-1021d includes four beam channels. Each beam channel includes at least one amplitude and phase unit, wherein each beam channel is used to connect an antenna. As an example, the amplitude and phase unit is a phase shifter 201a and / or an amplitude adjuster 201b, the phase shifter 201a is used to adjust the phase of the corresponding service signal based on the phase shift code, and the amplitude adjuster 201b is used to adjust the amplitude of the corresponding service signal based on the amplitude code, wherein the amplitude adjuster 201b includes, for example, an attenuator or a variable gain amplifier. In one example, the beam channel includes a phase shifter and an amplitude adjuster connected in series, so that both the phase and the amplitude of the corresponding service signal can be adjusted. Multiple antenna port groups are respectively connected to multiple beam channel groups, and are connected to the antenna array 103 to send the service signals output by the beam channel groups to the antenna array 103. In Figure 3 In the figure, four antenna port groups 104a-104d are illustrated, which are respectively connected to beam channel groups 1021a-1021d, and each antenna port group may include four antenna ports to send service signals to each antenna respectively. The number of antenna ports in the antenna port group may be the same as the number of beam channels.

[0028] Antenna array 103 is a dual-polarized antenna array. Figure 3 In , "X" represents a dual-polarized antenna, " / " represents a first polarized antenna, and "\" represents a second polarized antenna. A first polarized antenna and a second polarized antenna form a dual-polarized antenna. As an example, Figure 3 Only eight dual-polarized antennas are shown, and the eight dual-polarized antennas are arranged in two rows and constitute the antenna array 103. The first polarization is 90° orthogonal to the second polarization, for example: the first polarization may be vertical polarization, and the second polarization may be horizontal polarization; or, the first polarization may be horizontal polarization, and the second polarization may be vertical polarization; or, the first polarization may be 45° polarization, and the second polarization may be 135° polarization; or, the first polarization may be 135° polarization, and the second polarization may be 45° polarization.

[0029] The antenna array 103 includes a transmitting antenna array and a receiving antenna array. The transmitting antenna array is used to receive the service signal beamformed by the corresponding beam channel group from the corresponding radio frequency end and transmit it outward to the target object, and the receiving antenna array is used to receive the service signal reflected by the target object. For ease of explanation, unless otherwise specified, this article uses the transmitting antenna array as an example for description, but it can be understood that the principles of the transmitting antenna array and the receiving antenna array are similar, so the description of the transmitting antenna array can also be applied to the receiving antenna array.

[0030] The transmit antenna array includes multiple antenna groups, as an example, Figure 3 Only four antenna groups 1031a-1031d are shown, and each antenna group 1031a-1031d includes four antennas with the same polarization direction, wherein the four " / " antennas in the first row constitute the first polarized antenna group 1031a, the four " / " antennas in the second row constitute the first polarized antenna group 1031b, the four "\" antennas in the first row constitute the second polarized antenna group 1031c, and the four "\" antennas in the second row constitute the second polarized antenna group 1031d.

[0031] Continue as Figure 3 As shown, the four beam channel groups 1021a-1021d include two first beam channel groups (i.e., beam channel groups 1021a, 1021b) and two second beam channel groups (i.e., beam channel groups 1021c, 1021d), and the four antenna groups 1031a-1031d include two first polarization antenna groups (i.e., first polarization antenna groups 1031a, 1031b) and two second polarization antenna groups (i.e., second polarization antenna groups 1031c, 1031d).

[0032] Each first beam channel group is connected to a corresponding first polarized antenna group through a first antenna port group, and each second beam channel group is connected to a corresponding second polarized antenna group through a second antenna port group. Figure 3 In the embodiment, the beam channel group 1021a in the first beam channel group is connected to the first polarized antenna group 1031a through the first antenna port group 104a, the beam channel group 1021b in the first beam channel group is connected to the first polarized antenna group 1031b through the first antenna port group 104b, the beam channel group 1021c in the second beam channel group is connected to the second polarized antenna group 1031c through the first antenna port group 104c, and the beam channel group 1021d in the second beam channel group is connected to the second polarized antenna group 1031d through the first antenna port group 104d.

[0033] The first RF terminal 1011a is selected to two first polarized antenna groups 1031a, 1031b, and the second RF terminal 1011b is selected to two second polarized antenna groups 1031c, 1031d, so that the service signal from the first RF terminal 1011a and the service signal from the second RF terminal 1011b are 90° orthogonal and do not interfere with each other. If both service signals are communication signals, independent wireless channels are formed due to different polarizations, and the system capacity is increased by 1 times. If both service signals are perception signals, when the perception signal is irradiated to the target object, the characteristics of the target object itself will change the polarization state of the reflected electromagnetic wave signal. This phenomenon is called the "polarization change effect". By measuring the change in this polarization state, the physical properties of the target object, such as shape, structure and material, can be inferred, which can be applied to meteorological radars for detecting clouds and rain.

[0034] Therefore, there is an urgent need for a means to support the ISAC perception function on a communication system platform with low cost and high angular resolution.

[0035] Figure 4 and Figure 5 They are schematic diagrams of the structures of ISAC systems according to embodiments of the present invention.

[0036] Compared to Figure 3 , Figure 4 and Figure 5 The ISAC system in the communication system platform adds a switch 1022 to the beam control device 102. The switch 1022 may be a switch module including one or more switches. The switch 1022 is configured to selectively: In the communication stage, the first signal terminal 105a is selected to the first antenna port group 104a, 104b, and the second signal terminal 105b is selected to the second antenna port group 104c, 104d, so that the first radio frequency terminal 1011a is selected to the two first polarized antenna groups 1031a, 1031b, and the second radio frequency terminal 1011b is selected to the two second polarized antenna groups 1031c, 1031d. At this time, the first polarized antenna group 1031a, 1031b generates a first polarized beam, and the second polarized antenna group 1031c, 1031d generates a second polarized beam. The two beams are orthogonal and do not interfere with each other. Therefore, the two beams can carry different information. Therefore, during communication, the two polarized beams together form a complete communication beam, which is used to send to one user, thereby improving the communication capacity. Moreover, since the first polarized beam and the second polarized beam together form a complete communication beam, the transmission position of the communication beam is equivalent to the center position of the two groups of polarized antennas (including 8 first polarized antennas " / " and 8 first polarized antennas "\"), forming a virtual aperture. Alternatively, in the sensing stage, the first signal terminal 105a is selected to a first antenna port group (for example, the first antenna port group 104a), and the second signal terminal 105b is selected to another first antenna port group (for example, the first antenna port group 104b), so that the first RF terminal 1011a is selected to a first polarized antenna group (for example, the first polarized antenna group 1031a), and the second RF terminal 1011b is selected to another first polarized antenna group (for example, the first polarized antenna group 1031b). In which, because only one polarized beam can be used for sensing in the sensing stage, the first polarized antenna group 1031a forms an independent beam, and the first polarized antenna group 1031b forms another independent beam. The transmitting position of the beam of the first polarized antenna group 1031a is equivalent to the center position of the first polarized antenna group 1031a (the four first polarized antennas " / " located in the first row); the transmitting position of the beam of the first polarized antenna group 1031b is equivalent to the center position of the first polarized antenna group 1031b (the four first polarized antennas " / " located in the second row). Because the transmitting positions of the beams of the first polarized antenna group 1031a and the first polarized antenna group 1031b are different, two virtual apertures are formed, which can increase the virtual aperture of the transmitting antenna. Compared with the communication stage, the virtual aperture in the perception stage is doubled, which improves the angular resolution of the target object without increasing the number of antennas and reducing costs.

[0037] In some embodiments, one first polarized antenna group and another first polarized antenna group are located in different rows or in different columns. Each antenna group may have one or more antennas.

[0038] In some embodiments, the beam control device 102 is implemented in the form of a chip, or a part of the beam control device 102 is implemented in the form of a chip, and another part is implemented in the form of a PCB. When the beam control device 102 is implemented in the form of a chip, the antenna ports in the antenna port group may be pins of the chip, and the first signal terminal and the second signal terminal may also be pins of the chip; when the beam control device 102 is implemented in other forms, or when the beam control device 102 is integrated with the RF terminal and / or the antenna array in a chip, the antenna ports in the antenna port group may be the input terminal of the antenna or the output terminal of the beam channel, and the first signal terminal and the second signal terminal may be the output terminal of the RF terminal.

[0039] When the first RF terminal 1011a is selected to two first polarized antenna groups 1031a, 1031b, and the second RF terminal 1011b is selected to two second polarized antenna groups, the service signal from the first RF terminal 1011a and the service signal from the second RF terminal 1011b are 90° orthogonal and do not interfere with each other. At this time, the service signal is a communication signal, that is, the communication signal from different first RF terminals and second RF terminals can make the two polarized antennas form a beam, which can improve the communication capacity, so that the communication function of ISAC can be supported at a low cost on the communication system platform.

[0040] When the first RF end 1011a is selected to a first polarized antenna group 1031a, and the second RF end 1011b is selected to another first polarized antenna group 1031b, the service signal from the first RF end 1011a and the service signal from the second RF end 1011b have the same polarization direction. At this time, the service signal is a perception signal. Because for the ISAC system for detecting aerial target objects, it does not require the two perception signals to be 90° orthogonal. All perception signals are of the first polarization, that is, the perception signals from different first RF ends and second RF ends can make a polarized antenna form two beams, double the virtual aperture, and improve the angular resolution of the target, so that the perception function of ISAC can be supported at a low cost on the communication system platform.

[0047] like Figure 6 As shown, in one embodiment, the beam control device 200 also includes a first splitter 1023a and a second splitter 1023b. The input end of the first splitter 1023a is connected to the first signal end 105a, and the two output ends of the first splitter 1023a are connected to the two first beam channel groups 1021a, 1021b, which are used to split the service signal from the first RF end 1011a to the two first beam channel groups 1021a, 1021b.

In this embodiment, the switching switch 1022 is Figure 4 A specific implementation of the switching switch 1022 in the embodiment, in this implementation, the switching switch 1022 is further arranged between the RF terminals 1011a, 1011b and the splitters 1023a, 1023b.

[0048] Continue as Figure 6 As shown, in one embodiment, the switch 1022 includes a first switch 1022a and a second switch 1022b. The first end ① of the first switch 1022a is connected to the second signal end 105b, the second end ② of the first switch 1022a is connected to the input end of the second splitter 1023b, the third end ③ of the first switch 1022a is connected to the first end ① of the second switch 1022b, the second end ② of the second switch 1022b is connected to the first beam channel group 1021b, and the third end ③ of the second switch 1022b is connected to an output end of the first splitter 1023a. In some embodiments, the first switch 1022a and the second switch 1022b may be single-pole double-throw switches. Figure 6 The switching switch 1022 shown has a simple structure. It only needs to be set in two paths (the path between the second signal terminal 105b and the second splitter 1023b, and the path between the first splitter 1023a and the first beam channel group 1021b), which can effectively reduce the insertion loss.

[0049] like Figure 7 As shown, in the communication stage, when the first switching switch 1022a connects the first end ① and the second end ②, and the second switching switch 1022b connects the second end ② and the third end ③, the service signal (communication signal) from the first RF end 1011a is branched to the two first beam channel groups 1021a, 1021b via the two output ends of the first splitter 1023a, thereby being selected to the two first polarized antenna groups 1031a, 1031b, and the service signal (communication signal) from the second RF end 1011b is branched to the two second beam channel groups 1021c, 1021d via the two output ends of the first switching switch 1022a and the second splitter 1023b, thereby being selected to the two second polarized antenna groups 1031c, 1031d, wherein the first polarized antenna groups 1031a, 1031b and the second polarized antenna groups 1031c, 1031d are connected to the first polarized antenna groups 1031a, 1031b and 1031c, The center position of 1031d is the same, which can form a virtual aperture.

Compared with the communication stage, the virtual aperture in the perception stage is doubled, which improves the angular resolution of the target object without increasing the number of antennas and reducing costs.

[0051] Continue as Figure 6 As shown, in one embodiment, the fourth end ④ of the first switching switch 1022a is grounded to GND. When the first switching switch 1022a connects the first end ① and the fourth end ④, the service signal from the second RF terminal 1011b is selected to the ground GND via the first switching switch 1022a, thereby shutting off the service signal from the second RF terminal 1011b, and the antenna feed can be configured more flexibly. When there is no signal input in the second RF terminal 1011b, the second signal terminal 105b can be grounded to prevent signal reflection. More specifically, the fourth end of the first switching switch 1022a is grounded to GND via the matching resistor R1, and the resistance value of the matching resistor R1 is, for example, 50 ohms.

[0052] Figures 9 to 12 yes Figure 4 Another detailed structural diagram of the ISAC system is shown.

[0053] Compared to Figure 6 , in addition to the first switch 1022a and the second switch 1022b, Fig. 9 The switch 1022 in the embodiment further includes a third switch 1022c and a fourth switch 1022d. A first end ① of the third switch 1022c is connected to the first signal end 105a, a second end ② of the third switch 1022c is connected to the input end of the first splitter 1023a, a third end ③ of the third switch 1022c is connected to a first end ① of the fourth switch 1022d, a second end ② of the fourth switch 1022d is connected to an output end of the second splitter 1023b, and a third end ③ of the fourth switch 1022d is connected to a second beam channel group 1021c corresponding to an output end of the second splitter 1023b.

[0054] like Fig.10 As shown, in the communication stage, when the third switching switch 1022c is connected to the first end ① and the second end ②, and the fourth switching switch 1022d is connected to the second end ② and the third end ③, and when the first switching switch 1022a is connected to the first end ① and the second end ②, and the second switching switch 1022b is connected to the second end ② and the third end ③, the service signal from the first RF end 1011a is branched to the two first beam channel groups 1021a, 1021b via the two output ends of the first splitter 1023a, thereby being selected to the two first polarized antenna groups 1031a, 1031b, and the service signal from the second RF end 1011b is branched to the two second beam channel groups 1021c, 1021d via the two output ends of the first switching switch 1022a and the second splitter 1023b, thereby being selected to the two second polarized antenna groups 1031c, 1031d, which is suitable for transmitting communication signals.

[0055] like Fig.11 As shown, in the perception stage, when the third switching switch 1022c is connected to the first end ① and the second end ②, and the fourth switching switch 1022d is connected to the second end ② and the third end ③, and when the first switching switch 1022a is connected to the first end ① and the third end ③, and the second switching switch 1022b is connected to the first end ① and the second end ②, the service signal from the first RF end 1011a is branched to the first beam channel group 1021a via the other output end of the first splitter 1023a, thereby being selected to the first polarized antenna group 1031a, and the service signal from the second RF end 1011b is branched to the first beam channel group 1021b via the first switching switch 1022a and the second switching switch 1022b, thereby being selected to the first polarized antenna group 1031b, which is suitable for transmitting the perception signal.

[0056] like Fig.12 As shown, when the third switching switch 1022c is connected to the first end ① and the third end ③, and the fourth switching switch 1022d is connected to the first end ① and the third end ③, and when the first switching switch 1022a is connected to the first end ① and the second end ②, and the second switching switch 1022b is connected to the first end ① and the second end ②, the service signal from the first RF end 1011a is branched to the second beam channel group 1021c via the third switching switch 1022c and the fourth switching switch 1022d, thereby being selected to the second polarized antenna group 1031c, and the service signal from the second RF end 1011b is branched to the second beam channel group 1021d corresponding to an output end of the second splitter 1023b via the first switching switch 1022a and an output end of the second splitter 1023b, thereby being selected to the second polarized antenna group 1031d, which is suitable for transmitting the perception signal.

[0057] refer to Fig.11 and Fig.12 , compared to Figure 8 Due to the addition of the third switch 1022c and the fourth switch 1022d, two antenna groups with different polarizations can be time-division multiplexed. The two polarized antenna groups can form more beams and detect more information, and thus can also be used for weather radar.

[0058] Back to Fig. 9 , compared to Figure 6 In one embodiment, in addition to the fourth end ④ of the first switching switch 1022a being grounded to GND via the matching resistor R1, the fourth end ④ of the third switching switch 1022c is grounded to GND. When the third switching switch 1022c is connected to the first end ① and the fourth end ④, the service signal from the first RF terminal 1011a is selected to the ground GND via the third switching switch 1022c, thereby shutting off the service signal from the first RF terminal 1011a, and the antenna feed can be configured more flexibly. When there is no signal input in the first RF terminal 1011a, the first signal terminal 105a can be grounded to prevent signal reflection. More specifically, the fourth end of the third switching switch 1022c is grounded to GND via the matching resistor R2, and the resistance value of the matching resistor R2 is, for example, 50 ohms.

[0059] Back to Figure 4 and Figure 5 In one embodiment, when the beam is switched, the service switching signal is sent to the corresponding switch 1022 to connect the corresponding terminal of the switch 1022; the service switching signal may be a digital signal. In addition, the beam control code is sent to the corresponding beam channel group 1021, and the beam channel group 1021 adjusts the phase and / or amplitude of the corresponding service signal based on the beam control code to adjust the direction and / or shape of the beam; the beam control code may be a digital signal, as an example, the beam control code includes a phase shift code and / or an amplitude code, the phase shift code is a control signal for controlling the phase of the service signal, and the amplitude code is a control signal for controlling the amplitude of the service signal.

[0060] Specifically, during the period when the RF end 101 sends the first service signal to the beam control device 102, the selected beam channel group 1021 adjusts the phase and / or amplitude of the first service signal based on the first wave control code. When the service signal is switched to the second service signal, the service switching signal is sent to the switch 1022, and the selected beam channel group 1021 adjusts the phase and / or amplitude of the second service signal based on the second wave control code. The second service signal is a service signal that is located after the first service signal in the time domain, for example, Figure 2In the embodiment, the first service signal can be any symbol in the time domain, and the second service signal can be any symbol after the symbol, that is, the second service signal can be the first, second, or third symbol after the first service signal. For example, the first service signal can be symbol 1, and the second service signal can be symbol 2. It can be understood that when the beam of the second service signal changes with the beam of the first service signal, the second wave control code needs to be used to adjust the phase and / or amplitude of the second service signal. In one embodiment, within the cyclic prefix (CP) of the symbol where the second service signal is located, the service switching signal is sent to the switching switch 1022 to ensure that a suitable gating path is established before the second service signal is sent.

[0061] In one embodiment, the beam control device 102 includes a control interface 1024, and the service switching signal and the beam control code are respectively sent to the corresponding switch 1022 and the beam channel group 1021 via the control interface 1024. As an example, the control interface 1024 includes an SPI bus interface.

[0062] Fig.13 is a schematic diagram of a specific structure of a first switching switch and a third switching switch according to an embodiment of the present invention, wherein: Fig.13 The terminals ①, ②, ③, and ④ correspond to Figure 6-Figure 12 Terminals ①, ②, ③, and ④ of the first switching switch and the third switching switch.

[0063] like Fig.13 As shown, the first switch or the third switch includes: a first switch tube M1 to a fourth switch tube M4 and a first inverter INV1 and a second inverter INV2.

[0069] By setting the second inverter INV2, the switching states of the third switch tube M3 and the fourth switch tube M4 are always opposite, so that the service signal can only be output through one of the third switch tube M3 and the fourth switch tube M4.

[0070] The first switching switch or the third switching switch may further include input matching and output matching for impedance matching.

[0071] Fig.13 In the switching switch shown, the first switch tube M1 and the second switch tube M2 can be controlled by the same service switching signal 2, and the third switch tube M3 and the fourth switch tube M4 can be controlled by the same service switching signal 1, the control logic is simple, and the chip area is saved; compared with the third switch tube M3 and the fourth switch tube M4, the first switch tube M1 and the second switch tube M2 are arranged close to the end ①, and only the service switching signal 1 is needed to control the first switch tube M1 to be disconnected and the second switch tube M2 to be turned on, so that the ground switching can be easily realized.

[0072] In some embodiments, the second switch 1022b and the fourth switch 1022d are single-pole double-throw switches.

[0073] In some embodiments, Figure 4 The switch 1022 is not limited to using Figure 6The method shown is implemented, for example, the switching switch may also include a first switching switch and a second switching switch; the first end of the first switching switch is connected to the output end of the second splitter 1023b corresponding to the beam channel group 1021c, the second end of the first switching switch is connected to the second beam channel group 1021c, the third end of the first switching switch is connected to the first end of the second switching switch, the second end of the second switching switch is connected to the first beam channel group 1021b, and the third end of the second switching switch is connected to the output end of the first splitter 1023a corresponding to the beam channel group 1021b.

Based on the technical principles and concepts of the present invention, the switch 1022 may also adopt other reasonable structures, and the specific structure of the switch 1022 is not limited here.

[0076] Fig.15 Schematic diagram of the virtual aperture of the antenna array of the comparative embodiment.

[0077] like Fig.15As shown, the antenna array 103 includes a transmitting antenna array 1, a transmitting antenna array 2 and a receiving antenna array. These antenna arrays all use dual-polarized antennas, wherein the transmitting antenna array 1 and the transmitting antenna array 2 can both use the following Figure 3 The antenna array 103 shown in FIG. Figure 3 The antenna array 103 is a 2×4 array. Fig.15 The transmit antenna array 1 is a 2×4 array, and the transmit antenna array 2 is a 2×4 array. Figure 3 and Fig.15 When ISAC sensing is performed on the communication system platform, all the first polarized antennas " / " in the transmitting antenna array 1 receive a sensing signal transmitted by a radio frequency end, and the transmitting antenna array 1 forms a transmitting beam. All the first polarized antennas " / " in the transmitting antenna array 2 receive a sensing signal transmitted by a radio frequency end, and the transmitting antenna array 2 forms another transmitting beam. When the receiving antenna array includes four antennas, the system is called a 2T4R system. If the spacing between the two beams is 4d, and the spacing between the four antennas of the receiving antenna array is d, that is, the phase relationship of reception is satisfied, then the four receiving antennas are moved by 4d, and after being combined, they can be equivalent to two receiving antenna arrays, that is, equivalent to 2×4 receiving antennas, and the virtual aperture of the system is eight.

[0078] The dual-polarized transmission and reception does not gain any gain in the system's perceived angular resolution Δθ, where the angular resolution Δθ satisfies the following equation: , For the signal direction, is the number of receiving antenna groups, is the number of transmitting antenna groups, and the angular resolution Δθ is used to indicate the ability to perceive two different objects. As the number of antennas increases, the angular resolution Δθ begins to decrease, that is, two objects with a small distance between them can be perceived. However, increasing the number of transmitting or receiving antennas will increase costs.

[0079] Fig.16 It is a schematic diagram of the virtual aperture of the antenna array of an embodiment of the present application.

[0080] like Fig.16 As shown, the antenna array 103 includes a transmitting antenna array 1, a transmitting antenna array 2 and a receiving antenna array, wherein the transmitting antenna array 1 and the transmitting antenna array 2 can both adopt the following Figure 4 The antenna array 103 shown in FIG. Figure 4 The antenna array 103 is a 2×4 array. Fig.16In the embodiment, the transmitting antenna array 1 is a 2×4 array, and the transmitting antenna array 2 is a 2×4 array. In other embodiments, the number of transmitting antenna arrays is not limited to two, but may be three, four or more. The number of receiving antenna arrays is not limited to one, but may be two, three or more. The receiving antenna array may be located between any two different transmitting antenna arrays. When both the transmitting antenna array and the receiving antenna array include multiple arrays, different receiving antenna arrays may be located between different transmitting antenna arrays.

[0081] Combination Figure 4 and Fig.16 When ISAC perception is performed in the ISAC system, by switching, all the first polarized antennas “ / ” in the transmitting antenna array 1 can receive the perception signals transmitted by the two RF ends, and the transmitting antenna array 1 forms two transmitting beams. All the first polarized antennas “ / ” in the transmitting antenna array 2 receive the perception signals transmitted by the two RF ends, and the transmitting antenna array 2 forms another two transmitting beams.

[0082] Fig.16 The transmitting antenna array 1 in the figure includes two rows of antenna groups with the same polarization from top to bottom, wherein one sensing signal is fed into the first row of antenna groups of the transmitting antenna array to form a transmitting beam; the other sensing signal is fed into the second row of antenna groups of the transmitting antenna array to form another transmitting beam, so that the transmitting antenna array 1 forms two transmitting beams; similarly, the transmitting antenna array 2 also forms two transmitting beams. Therefore, the transmitting antenna arrays 1 and 2 form a total of 4 transmitting beams. When the receiving antenna array includes four antennas, the system is called a 4T4R system. When the receiving phase relationship is met, they can be combined to be equivalent to four receiving antenna arrays, that is, equivalent to 4×4 receiving antennas. The virtual aperture of the system is sixteen, compared to Fig.15 The virtual aperture is doubled.

[0083] Since the equivalent number of transmitting antennas is doubled, the angular resolution Δθ is also doubled, but the actual number of transmitting antennas is not increased, that is, the cost is not increased.

[0084] In other embodiments, the transmit antenna array is not limited to a 2×4 array, but may also be a 4×4 array, or an array of other numbers. In one embodiment, in a first direction (e.g., a vertical direction), a portion of the first polarized antenna group and another portion of the first polarized antenna group are spaced apart from each other. For example, when the transmit antenna array is a 4×4 array, in the sensing stage, one sensing signal is fed into the first row and the third row of the transmit antenna array, and another sensing signal is fed into the second row and the fourth row of the transmit antenna array, that is, the antenna corresponding to one sensing signal and the antenna corresponding to another sensing signal are spaced apart from each other. In one embodiment, in a first direction (for example, a vertical direction), a portion of the multiple first polarized antenna groups and another portion of the multiple first polarized antenna groups are located at two end sides of the antenna array. For example, when the transmitting antenna array is a 4×4 array, in the sensing stage, one sensing signal is fed into the first row antenna group of the transmitting antenna array, and the other sensing signal is fed into the fourth row antenna group of the transmitting antenna array, thereby maximizing the spacing between the two sensing signals. The two orthogonal sensing signals are radiated from the two end sides of the receiving antenna array, respectively, thereby forming a larger virtual aperture and further improving the angular resolution Δθ.

[0085] In this scheme, if Fig.16 As shown, in the first direction (such as Fig.16 In the longitudinal direction, the receiving antenna array is placed in the middle of the transmitting antenna array, and two orthogonal sensing signals are radiated from both sides of the receiving antenna array, which can form a larger virtual aperture and thus improve the angular resolution.
