Description

Technical Field

[0001] This solution involves radar technology and can be applied to fields such as autonomous driving, intelligent driving, surveying and mapping, smart homes, or smart manufacturing, and in particular, it relates to a wireless transceiver device. Background Technology

[0002] Radar systems can transmit signals and obtain the echo signals of those signals on the surface of a target object, thereby determining the spatial distance of the target object based on the frequency changes or flight time of the echo signals. Due to its high detection efficiency and range resolution, radar is widely used in many fields such as deep space exploration, transportation, and disaster relief, playing a vital role in the civilian sector.

[0003] The radar transmitter generates radio frequency signals, which are transmitted to a directional antenna via a transceiver switch and radiated outwards as electromagnetic waves. Under the control of the antenna control equipment, the electromagnetic waves scan space in a specified direction. When the electromagnetic waves illuminate a target, a portion of the secondary scattered electromagnetic waves reaches the radar antenna, passes through the transceiver switch to the receiver, and are amplified, mixed, and detected before being sent to the radar terminal equipment to detect the target's presence, azimuth, range, and velocity.

[0004] Currently, in scenarios requiring higher resolution, it is necessary to significantly increase the number of radar transmit and receive channels, which is costly. There is currently a lack of wireless transceiver devices that can improve angular resolution. Summary of the Invention

[0005] This application provides a wireless transceiver device. The wireless transceiver device includes: a transmitting antenna array, comprising a first transmitting antenna and a second transmitting antenna, the first and second transmitting antennas being used to transmit radio frequency signals and sharing a first transmitting channel; a first receiving antenna array, used to receive echo signals from the radio frequency signals, the first receiving antenna array including at least one receiving antenna; and a first switch, through which at least two transmitting antennas switch between using the first transmitting channel.

[0006] The embodiments of this application can achieve time-division multiplexing of the transmission channel by having multiple transmitting antennas share a single transmission channel, thereby obtaining a larger virtual array and improving the angular resolution of the wireless transceiver device.

[0007] In a first aspect, embodiments of this application disclose a wireless transceiver device, the device comprising:

[0008] A transmitting antenna array, comprising a first transmitting antenna and a second transmitting antenna, wherein the first transmitting antenna and the second transmitting antenna are used to transmit radio frequency signals and share a first transmitting channel;

[0009] A first receiving antenna array is used to receive the echo signal of the radio frequency signal, and the first receiving antenna array includes at least one receiving antenna.

[0010] The first switch allows the at least two transmitting antennas to switch between using the first transmitting channel.

[0011] In this embodiment, the first and second transmitting antennas in the wireless transceiver share the first transmitting channel via a first switch. Therefore, the wireless transceiver can transmit radio frequency signals from the first transmitting channel through different transmitting antennas at different time periods. Implementing this embodiment can reduce the number of transmitting channels, enabling time-division multiplexing of the transmitting channels and obtaining a virtual array with more array elements, thereby improving the angular resolution of the wireless transceiver. It should be noted that the more virtual arrays there are, the higher the angular resolution of the wireless transceiver.

[0012] In conjunction with the first aspect, in one possible implementation, the apparatus further includes:

[0013] A second receiving antenna array is used to receive the echo signal of the radio frequency signal, and the second receiving antenna array includes at least one receiving antenna.

[0014] At least one second switch is provided, through which the receiving antennas in the first receiving antenna array and the receiving antennas in the second receiving antenna array switch to use the same receiving channel.

[0015] In this embodiment, some or all of the receiving antennas in the first receiving antenna array and some or all of the receiving antennas in the second receiving antenna array can share a receiving channel via a second switch. In this embodiment, at least two transmitting antennas share a transmitting channel, and at least two receiving antennas share a receiving channel. Therefore, the wireless transceiver can simultaneously perform time-division multiplexing of the transmitting and receiving channels via the switch, saving the number of transmitting and receiving channels. This allows for simultaneous time-division multiplexing of both transmitting and receiving channels, resulting in a virtual array with more array elements, thereby improving the angular resolution of the wireless transceiver.

[0017] The third transmitting antenna is used to transmit radio frequency signals from the second transmitting channel. The first transmitting antenna and the third transmitting antenna are arranged along a first direction, and the second transmitting antenna and the third transmitting antenna are arranged along a second direction. The first direction is perpendicular to the second direction.

[0018] In this embodiment, the wireless transceiver may further include a third transmitting antenna connected to only one transmitting channel. The third transmitting antenna can form different operating states of the wireless transceiver with the first transmitting antenna and the second transmitting antenna to obtain different virtual arrays. Furthermore, based on the aforementioned different virtual arrays, a synthetic virtual array with a larger number of array elements can be synthesized. In some scenarios, a third transmitting antenna can also be added to reduce the number of switches.

[0024] In addition, during a second time period, the first switch is controlled to turn on the second transmitting antenna and the transmitting channel, and radio frequency signals are transmitted through the second transmitting antenna. The second time period is the time period after the first time period.

[0025] In this embodiment of the application, the wireless transceiver can transmit the radio frequency signal of the first transmission channel through different transmitting antennas at different time periods through the controller. The wireless transceiver can also receive the echo signal through different receiving antennas at different time periods through the controller, so as to realize the time division multiplexing of the transmission channel and the receiving channel.

[0026] In conjunction with the first aspect, in one possible implementation, the device further includes a signal processing module, which is used to splice the echo signal of the radio frequency signal transmitted by the first transmitting antenna and received by the first receiving antenna array from the echo signal of the radio frequency signal transmitted by the second transmitting antenna, based on time sequence, to obtain a composite signal.

[0027] In this embodiment, the wireless transceiver expands the size of the virtual array by increasing the number of transmitting antennas corresponding to a transmitting channel, thereby obtaining echo signals with a larger data volume.

[0028] In conjunction with the first aspect, in one possible implementation, the device further includes a data processing module, which is used to process the echo signal of the radio frequency signal transmitted by the first transmitting antenna received by the first receiving antenna array to obtain point cloud data corresponding to the first transmitting antenna.

[0029] The echo signal of the radio frequency signal transmitted by the second transmitting antenna received by the first receiving antenna array is processed to obtain the point cloud data corresponding to the first transmitting antenna.

[0030] The point cloud data corresponding to the first transmitting antenna and the point cloud data corresponding to the second transmitting antenna are superimposed to obtain the superimposed point cloud data.

[0031] In this embodiment of the application, the wireless transceiver can synthesize point cloud data to obtain synthesized point cloud data. The increased amount of synthesized point cloud data can improve the signal-to-noise ratio.

[0115] Please see Figure 9 , Figure 9 This is a schematic diagram of the structure of a wireless transceiver device 40 provided in an embodiment of this application.

[0116] like Figure 9 As shown, the wireless transceiver 40 includes a transmitting antenna 401, a receiving antenna 402, and a switch 403. Wherein:

[0117] The transmitting antenna 401 includes antennas T0, T1, and T1-, wherein T0, T1, and T1- are used to transmit radio frequency signals through the same transmitting channel.

[0118] The receiving antenna 402 includes antennas R0, R1, R2, R3, R1-, R2-, and R3-, and the positions of each antenna can be as follows: Figure 8 As shown, antennas R0, R1, R2, and R3 are arranged horizontally at equal intervals, and antennas R0, R1-, R2-, and R3- are arranged vertically at equal intervals. R0, R1, R2, R3, R1-, R2-, and R3- are used to transmit the received echo signals to the same receiving channel.

[0119] Switch 303 includes switch A and switch B. Switch A is used to control the connection between the transmitting antenna 401 and the transmitting channel, and switch B is used to control the connection between the receiving antenna 402 and the receiving channel.

[0120] Based on the aforementioned switches A and B, the wireless transceiver 40 can have multiple operating states. For example, switch A is connected to R0, and switch B is connected to T0; or switch A is connected to R2-, and switch B is connected to T1-; or switch A is connected to R3, and switch B is connected to T1.

[0121] Furthermore, different virtual arrays can be obtained based on the different operating states of the wireless transceiver device 40. By combining the different virtual arrays, a composite virtual array can be obtained. For details, please refer to the relevant content of the wireless transceiver device 30, which will not be repeated here.

[0122] The following is combined Figure 10 This application provides a specific control method based on its embodiments.

[0123] Specifically, this method can be applied to the wireless transceiver devices mentioned above, such as... Figure 10 As shown, the control method includes some or all of the following steps:

[0124] S101, In the first time period, control the first switch to turn on the first transmitting antenna and the first transmitting channel, and transmit radio frequency signals through the first transmitting antenna.

[0125] In one implementation, the wireless receiving device can receive a user operation, and in response to the user operation, the wireless receiving device controls a first switch to turn on the first transmitting antenna and the first transmitting channel, and transmits a radio frequency signal through the first transmitting antenna.

[0126] Taking the wireless transceiver 30 as an example, the transmitting antennas T1 and T1- in the wireless transceiver 30 are used to transmit the second radio frequency signal of the second transmission channel. T1 and T1- share the second transmission channel and are connected to the second transmission channel through switch D. Specifically, the wireless transceiver 30 can control switch D to state ① during a first time period. At this time, the transmitting antenna T1 is connected to the second transmission channel, and the wireless transceiver 30 transmits the second radio frequency signal of the second transmission channel through the transmitting antenna T1. At this time, the transmitting antenna of the wireless transceiver 30 includes antenna T0 and antenna T1. Furthermore, the wireless transceiver can also control antenna T0 to transmit the first radio frequency signal of the first transmission channel in the first cycle and control antenna T1 to transmit the second radio frequency signal of the second transmission channel in the second cycle. The signal waveform transmitted by the wireless transceiver during the first time period can be seen in [reference needed]. Figure 7 As shown in (A), the first waveform from left to right can represent the first radio frequency signal of the first transmission channel transmitted by antenna T0 in the first period, and the second waveform can represent the second radio frequency signal of the second transmission channel transmitted by antenna T1 in the second period.

[0127] S102. Receive the first echo signal of the radio frequency signal transmitted by the first transmitting antenna through the first receiving antenna array.

[0128] In some embodiments, the wireless transceiver can receive a first echo signal of a radio frequency signal transmitted by a first transmitting antenna via a first receiving antenna array.

[0129] In other embodiments, the wireless transceiver first determines a receiving array, and then receives the first echo signal of the radio frequency signal transmitted by the first transmitting antenna through the determined receiving array.

[0130] For example, a wireless transceiver includes a second switch, a first receiving array, and a second receiving array. The wireless transceiver can first control the first switch to determine the first receiving array as the receiving array for a first time period. For example, see wireless transceiver 30. Figure 3 The wireless transceiver 30 can control switches A, B, and C to state ① during the first cycle. At this time, the first receiving array consists of R0, R1, R2, and R3. The operating state of the wireless transceiver 30 at this time is... Figure 4A As shown, the virtual array corresponding to the wireless transceiver 30 is as follows: Figure 4B As shown. Figure 7 The wireless transceiver 30 can receive echo signals from antennas R0, R1, R2 and R3, and receive the first echo signals H-r0, H-r1, H-r2 and H-r3.

[0131] S103. In the second time period, control the first switch to turn on the second transmitting antenna and the transmitting channel, and transmit radio frequency signals through the second transmitting antenna. The second time period is the time period after the first time period.

[0132] Specifically, after the first time period ends, the wireless transceiver can switch the first switch to control the second transmitting antenna and the transmitting channel to transmit radio frequency signals through the second transmitting antenna.

[0133] Optionally, the time difference between the first time period and the second time period shall not exceed a preset duration. It may be understood that in some scenarios, an excessively long time difference between the first and second time periods can cause the target to change, making it impossible to obtain echo signals of radio frequency signals emitted by different transmitting antennas targeting that target.

[0134] Taking the wireless transceiver 30 as an example, specifically, the wireless transceiver 30 can control switch D to state ② during the second cycle. At this time, the transmitting antenna T1- is connected to the second transmitting channel, and the wireless transceiver 30 transmits the second radio frequency signal of the second transmitting channel through the transmitting antenna T1-. At this time, the transmitting antenna of the wireless transceiver 30 includes antenna T0 and antenna T1-. Furthermore, the wireless transceiver can also control antenna T0 to transmit the first radio frequency signal of the first transmitting channel in the fourth cycle, and control antenna T1- to transmit the second radio frequency signal of the second transmitting channel in the fourth cycle. The signal waveform transmitted by the wireless transceiver during the second time period can be seen in [reference needed]. Figure 7 As shown in (A), the third waveform from left to right can represent the first radio frequency signal of the first transmission channel transmitted by antenna T0 in the third cycle, and the fourth waveform can represent the second radio frequency signal of the second transmission channel transmitted by antenna T1 in the fourth cycle.

[0135] S104. Receive the second echo signal of the radio frequency signal transmitted by the second transmitting antenna through the first receiving antenna array.

[0136] In some embodiments, the wireless transceiver can receive the second echo signal of the radio frequency signal transmitted by the second transmitting antenna through the first receiving antenna array.

[0137] In other embodiments, the wireless transceiver includes a first receiving array and a second receiving array. The wireless transceiver can first control a first switch to determine the receiving array within a first time period. Taking wireless transceiver 30 as an example, the wireless transceiver can control switches A, B, and C to be in state ② within the first cycle time. At this time, the first receiving array is R0, R1-, R2-, and R3-. The operating state of wireless transceiver 30 at this time is... Figure 5A As shown, the virtual array corresponding to the wireless transceiver 30 is as follows: Figure 5B As shown.

[0138] S105. Based on the time sequence, the first echo signal and the second echo signal are spliced ​​together to obtain the composite signal.

[0139] Specifically, the wireless transceiver can splice the first and second echo signals according to the order of the received echo signals to obtain a composite signal. It is understood that, in the case of limited channel resources, this embodiment can obtain a composite signal with more data by using at least two transmitting antennas sharing a single transmitting channel. Furthermore, the wireless transceiver can use this composite signal to determine the target's position and angle, etc.

[0140] For example, see the wireless transceiver device 30. Figure 7 (B) in the middle Figure 7 (B) in the example illustrates the splicing process of receiving echo signals in two operating states of the wireless transceiver 30. Further details are omitted here.

[0158] The GPIO interface can be configured via software. It can be configured as a control signal or a data signal. In some embodiments, the GPIO interface can be used to connect the processor 110 to a camera 193, a display screen 194, a wireless communication module 160, an audio module 170, a sensor module 180, etc. The GPIO interface can also be configured as an I2C interface, an I2S interface, a UART interface, a MIPI interface, etc.

The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to the application processor. The application processor outputs sound signals through an audio device (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through the display screen 194. In some embodiments, the modem processor may be a separate device. In other embodiments, the modem processor may be independent of the processor 110 and may be housed in the same device as the mobile communication module 150 or other functional modules.

[0173] The ISP (Image Signal Processor) is used to process data fed back from the camera 193. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set in the camera 193.

[0174] Camera 193 is used to capture still images or videos. An object is projected onto a photosensitive element by generating an optical image through the lens. The photosensitive element can be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP for processing. The DSP converts the digital image signal into image signals in standard RGB, YUV, or other formats. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0186] Pressure sensor 180A is used to sense pressure signals and convert them into electrical signals. In some embodiments, pressure sensor 180A can be disposed on display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, and capacitive pressure sensors. A capacitive pressure sensor may include at least two parallel plates with conductive material. When force is applied to pressure sensor 180A, the capacitance between the electrodes changes.

Electronic device 100 can also calculate the touch position based on the detection signal from pressure sensor 180A. In some embodiments, touch operations applied to the same touch position but with different touch operation intensities can correspond to different operation commands. For example, when a touch operation with an intensity less than a first pressure threshold is applied to the SMS application icon, a command to view an SMS is executed. When a touch operation with an intensity greater than or equal to the first pressure threshold is applied to the SMS application icon, a command to create a new SMS is executed.

[0187] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 100. In some embodiments, the gyroscope sensor 180B can determine the angular velocity of the electronic device 100 about three axes (i.e., the x, y, and z axes). The gyroscope sensor 180B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the shake of the electronic device 100, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shake of the electronic device 100 by moving in the opposite direction, thus achieving image stabilization.

[0202] In this embodiment, the electronic device 100 can execute the above-described control method through the processor 110 to obtain a synthesized signal.

[0203] Figure 12 This is a software structure block diagram of an electronic device 100 disclosed in an embodiment of this application.

[0204] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the system is divided into four layers, from top to bottom: the application layer, the application framework layer, the runtime and system libraries, and the kernel layer.

[0205] The application layer can include a series of application packages.

[0206] like Figure 12 As shown, the application layer also includes a wireless transceiver module. The application package can include applications (also known as applications) such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and SMS.

[0207] The application framework layer provides application programming interfaces (APIs) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0208] like Figure 12 As shown, the application framework layer may include a window manager, content provider, view system, phone manager, resource manager, notification manager, etc.

[0209] The window manager is used to manage windowed applications. It can retrieve screen size, determine the presence of a status bar, lock the screen, and capture screenshots, among other things.

[0210] Content providers store and retrieve data, making that data accessible to applications. This data may include videos, images, audio, made and received phone calls, browsing history and bookmarks, phone books, etc.

[0211] A view system includes visual controls, such as controls for displaying text and controls for displaying images. View systems can be used to build applications. A display interface can consist of one or more views. For example, a display interface including a text notification icon could include views for displaying text and views for displaying images.

[0212] The phone manager is used to provide communication functions for electronic device 100. For example, it manages call status (including connection and disconnection).

[0213] The file explorer provides applications with various resources, such as localized strings, icons, images, layout files, video files, and more.

[0214] The notification manager allows applications to display notifications in the status bar. These notifications can be used to deliver informational messages and can disappear automatically after a short pause, requiring no user interaction. For example, the notification manager can be used to notify users of completed downloads or message alerts. The notification manager can also display notifications as icons or scrolling text in the top status bar, such as notifications from background applications, or as dialog-style notifications on the screen. Examples include displaying text messages in the status bar, emitting sounds, vibrating electronic devices, and flashing indicator lights.

[0215] The runtime consists of the core libraries and the virtual machine. The runtime is responsible for system scheduling and management.

[0216] The core library consists of two parts: one part is the functionalities that the programming language (e.g., Java) needs to call, and the other part is the system's core library.

[0217] The application layer and application framework layer run in a virtual machine. The virtual machine executes the programming files (e.g., .jave files) of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0218] System libraries can include multiple functional modules. For example: surface manager, media libraries, 3D graphics processing libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), etc.

[0219] The Surface Manager is used to manage the display subsystem and provides the fusion of two-dimensional (2D) and three-dimensional (3D) layers for multiple applications.

[0220] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0221] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0222] A 2D graphics engine is a graphics engine for 2D drawing.

[0223] The kernel layer is the layer between hardware and software. The kernel layer includes at least the display driver, camera driver, audio driver, sensor driver, and virtual card driver.

[0224] The following example, using a scene of capturing a photograph, illustrates the workflow of the software and hardware of the electronic device 100.

[0225] When touch sensor 180K receives a touch operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including touch coordinates, timestamp of the touch operation, etc.). The raw input event is stored in the kernel layer. The application framework layer retrieves the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking a touch click as an example, where the corresponding control is the camera application icon, the camera application calls the application framework layer's interface to launch the camera application, and then calls the kernel layer to launch the camera driver, capturing still images or videos through camera 193.

[0226] In the above embodiments, all or part of the functions can be implemented by software, hardware, or a combination of software and hardware. When implemented using software, it can be implemented entirely or partially in the form of a computer program product. The computer program product includes one or more computer instructions.
