[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0035] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0036] In related technologies, with the gradual promotion of phased array radars based on millimeter-wave chips in civil fields such as automobiles and transportation, higher requirements have been placed on the angular resolution of radars. In order to improve the angular resolution of radars, the RF channel formed by the cascade of millimeter-wave chips needs to ensure the coherence during the cascade, which requires that the local oscillator signal generated by the master chip can be fed into the local oscillator input terminals of the master chip and the slave chip with equal length. However, with the expansion of the scale of millimeter-wave chips, it is difficult to ensure the equal length of the local oscillator line in large-scale phased circuits. Reference Figure 1 As shown, a conventional array method is used to construct a continuous wave phased array radar by cascading millimeter wave chips. The transmitting end 100 and the receiving end 110 have the same number of chips. It is necessary to ensure that the feed lines of the local oscillator input units (LO_IN) of each chip cascade are of equal length to achieve effective coherence. Among them, the transmitting end 100 includes: a millimeter wave master chip 121, a first millimeter wave slave chip 122; the receiving end includes a second millimeter wave slave chip 123 and a third millimeter wave slave chip 124. Each chip includes: a chip local oscillator generating unit (Frequency Generator, FG) 131, a chip local oscillator cascade output unit (FMCW_OUT), a chip local oscillator cascade switching unit (FMCW_IN) 133, and a chip local oscillator cascade input unit (LO_IN) 134. Since it is difficult to achieve equal length of feed lines between the master chip and the slave chip when the number of slave chips is large, large-scale cascading is limited.

[0037] In view of the shortcomings and deficiencies of the prior art, this exemplary embodiment provides a phased array radar design method to achieve a low-cost and high-angle resolution phased array radar design method. Figure 2 As shown, the phased array radar design method may specifically include the following steps:

[0038] Step S11, determining the target transmission power of the corresponding radar according to the detection range configuration parameters of the target scene;

[0039] Step S12, determining a detection mode according to the target transmission power and the maximum output power of the transmitting antenna;

[0040] Step S13, based on the correspondence between the radar chip and the transmitting antenna of the radar, determining the cascade circuit configuration parameters corresponding to the detection mode; wherein the cascade circuit configuration parameters include the number of master chips and slave chips, and receiving / transmitting functions.

[0041] Below, each step of the phased array radar design method in this example implementation will be described in more detail with reference to the accompanying drawings and embodiments.

[0042] In step S11, the target transmission power of the corresponding radar is determined according to the detection range configuration parameters of the target scene.

[0043] Exemplarily, the detection range configuration parameters include: detection distance and angular resolution.

[0044] Exemplarily, the above-mentioned determination of the target transmission power of the corresponding radar according to the detection range configuration parameter of the target scene may specifically include:

[0045] The target transmission power is determined according to the detection distance and the angular resolution in combination with the transmitting antenna gain and the receiving antenna gain of the radar.

[0046] For example, the above-mentioned target scenario can be a vehicle-mounted radar detection scenario, or a drone detection application scenario, etc.; it can also be a pedestrian / non-motor vehicle detection, or a vehicle detection application scenario; in addition, it can also be a security application scenario.

[0047] The user can create a radar configuration task for the current target scene on the smart terminal device, and configure the detection range configuration parameters corresponding to the target scene according to actual business needs. The terminal device executes the task and determines the target transmit power of the radar based on the detection range parameters of the target scene and the characteristic parameters of the existing radar equipment. The target transmit power can meet the predefined detection range requirements.

[0048] Specifically, the radar can be used to detect the target based on its detection distance R and angular resolution θ. 3dB The radar transmit power required is calculated according to the radar equation. The specific formula may include:

[0049]

[0050] Where R is the detection target distance; P r G is the radar received echo energy, which is related to the signal-to-noise ratio required for detecting the target; t is the transmitting antenna gain, G r is the receiving antenna gain, λ is the radar wavelength, and σ is the radar reflection cross-sectional area.

[0051] Where, the transmitting antenna gain G t and the receiving antenna gain Gr With the radar angle resolution θ 3dB Related; Radar transmit power P t Mainly determined by the detection target distance R and the transmitting antenna gain G t and the transmitting antenna gain G r Decide.

[0052] In step S12, a detection mode is determined according to the target transmission power and the maximum output power of the transmission antenna.

[0053] Exemplarily, the current detection mode may be configured according to the currently determined target transmission power in combination with the maximum output power of the transmitting antenna.

[0054] Specifically, the detection mode may include pre-configured: long-range detection mode, short-range detection mode.

[0055] In step S13, based on the correspondence between the radar chip and the transmitting antenna of the radar, the cascade circuit configuration parameters corresponding to the detection mode are determined; wherein the cascade circuit configuration parameters include the number of master chips and slave chips, and receiving / transmitting functions.

[0056] Exemplarily, for an existing millimeter-wave radar device, the transmitting end may include at least one master chip and several slave chips; similarly, the receiving end may include at least one master chip and several slave chips; each chip at the transmitting end may be coupled with multiple transmitting antennas, and each chip at the receiving end may be coupled with multiple receiving antennas.

[0057] Specifically, the cascade circuit forms corresponding to the long-range detection mode and the short-range detection mode can be pre-configured. For example, the long-range detection mode can be configured as a cascade circuit with a single master chip receiving and multiple slave chips transmitting; the short-range detection mode can be configured as a cascade circuit with a single master chip transmitting and multiple slave chips receiving.

[0058] For example, each of the selected millimeter wave chips contains N transmission channels, and the maximum output power of each transmission channel is C t If the current judgment is NC t ≤P t , it can be configured as a short-range detection mode, and a cascade circuit with a single master chip transmitting and multiple slave chips receiving is used. t >P t , it can be configured as a remote detection mode, and a cascade circuit with a single master chip receiving multiple slave chips transmitting is used. Let the number of cascaded transmitting slave chips be M, then M = Ceil (P t / NC t ), Ceil is the rounding symbol.

[0059] Of course, in some exemplary embodiments, if the target transmission power is large, in the long-range detection mode, a cascade circuit with multiple master chips receiving and multiple slave chips transmitting can also be configured. The number of corresponding master chips receiving can be calculated and configured according to the target transmission power and the maximum output power of each transmitting antenna. Alternatively, if the target transmission power is small, for example, the target transmission power is less than a preset threshold, in the short-range detection mode, a cascade circuit with a single master chip transmitting and a single slave chip receiving can also be configured.

[0060] Exemplarily, the method further includes: determining a feeding method of a local oscillator signal between an antenna transmitting end and an antenna receiving end according to the cascade circuit configuration parameters.

[0061] Exemplarily, the local oscillator feed lines between the multiple slave chips are configured with equal lengths.

[0062] Specifically, in the scenario where long-range detection is a cascade circuit with a single master chip receiving and multiple slave chips transmitting, and short-range detection is a cascade circuit with a single master chip transmitting and multiple slave chips receiving, the cascade of the LO local oscillator signal only needs to ensure that the local oscillator feed lines between the slave chips are of equal length, and the master chip adopts the LO access method of chip internal feeding. That is, for the long-range detection mode, the local oscillator source is fed from the receiving end master chip to the transmitting end slave chip, and for short-range detection, the local oscillator source is fed from the transmitting end master chip to the receiving end slave chip.

[0063] Exemplarily, the method further includes:

[0064] Step S14, synthesizing the current radar transmit / receive pattern, and performing performance verification using the detection range configuration parameters of the target scene.

[0065] Specifically, based on the configuration results of the current transceiver antenna and the cascade circuit, the corresponding radar transceiver pattern can be synthesized, and the radar detection area can be covered through wave control scanning. Among them, for the long-range detection mode, the radar angle resolution θ 3dB Mainly determined by the antenna layout of the transmitting end; for short-range detection radar, the angular resolution θ 3dB Mainly determined by the antenna layout at the receiving end.

[0066] For the radar transmit and receive pattern, the design results of the current phased array radar can be verified using the pre-configured detection range configuration parameters.

[0067] In an exemplary embodiment, each radar chip of the current radar includes 8 transmitting channels or 8 receiving channels, and the transmitting power C of each channel is t =10mW. If the current mission scenario requires the radar to detect the target at a distance of R = 500m, the angle resolution requirement is θ 3dB =4°, the required radar transmission power is calculated to be P t= 200mW. Based on the calculation result, a cascade circuit is constructed using the remote detection mode.

[0068] refer to Figure 3 As shown, based on the determined long-range detection mode, a cascade circuit of 1 receiving master chip and 3 transmitting slave chips is used accordingly. The local oscillator signal is generated by the master chip 231. Since the receiving end has only one millimeter-wave chip on the master chip to receive electromagnetic waves, the local oscillator signal can be fed inside the chip at the master chip end instead of being fed from the LO_IN port. The three slave chips (232, 233, 234) feed the local oscillator signal fed from the FMCW_OUT port of the master chip 231 through their respective LO_IN ports, and the three feed lines must be of equal length. Compared with the prior art, the millimeter-wave chip cascade design of this method adopts an equal-length power division from the FMCW_IN port to the FMCW_OUT port, so it is relatively Figure 1 The prior art shown is more suitable for large-scale chip cascading.

[0069] The four chips at the radar transmitter end are connected to a total of 24 antenna radiation elements to achieve radar beam transmission. The directional diagram at 0° is as follows: Figure 4 As shown by the dotted line in the figure; a chip at the receiving end is connected to 8 antenna radiation array elements to realize radar beam reception. The directional diagram at the 0° direction is shown in Figure 4 The solid line shows.

[0070] The synthetic radar transmit and receive pattern, the radar synthetic pattern 0° points as follows Figure 5 As shown, it can be seen that the synthetic direction diagram is Figure 4 The solid line in the figure shows that the 0° direction is close to the synthetic direction pattern, which satisfies the angular resolution θ 3dB =4° requirement.

[0071] The phased array radar design method provided by the present invention can configure the long-range detection mode or short-range detection mode corresponding to the current use scenario according to the target transmission power. The construction of the millimeter-wave radar radio frequency channel is realized by cascading millimeter-wave chips. For long-range detection, a cascade circuit with a single master chip receiving and multiple slave chips transmitting is constructed. For short-range detection, a cascade circuit with a single master chip transmitting and multiple slave chips receiving is constructed. The fully coherent waveform of the radar system comes from the local oscillator signal generated by the master chip. The local oscillator signal is fed into the slave chip with equal length, and the transmitting and receiving antenna radiation patterns are synthesized to realize the radar scanning beam that meets the design requirements. Thereby, large-scale integration is easily achieved. This method can be widely used in low-cost high-angle resolution radar systems. By configuring different cascade points for different modes, a detection radar with high angle resolution is realized.
