The remote radar detection method comprises the following steps:
the method for detecting the long-distance radar in the embodiment of the application, as shown in fig. 1, includes the following steps:
step S101: and controlling the radar transmitting end to generate a synthesized transmitting signal and inputting the synthesized transmitting signal into a target input port of the barrett matrix, wherein the synthesized transmitting signal is synthesized by transmitting signals of at least two paths of transmitting channels.
The synthesized transmitting signals are generated after power synthesis is carried out on transmitting signals of at least two paths of transmitting channels, and the power of transmitting signals sent by each path of transmitting channels is equal. Specifically, at least two paths of transmitting channels transmit equal-power transmitting signals to a power synthesizer, and the power synthesizer is controlled to perform power synthesis on all the equal-power transmitting signals to generate synthesized transmitting signals.
The Butler matrix (Butler matrix) is a feed network with multiple inputs and multiple outputs, and an n×n Butler matrix feed network has N input ports and N output ports, where when one input port feeds, the N output ports can realize constant amplitude output, and the phase differences of adjacent output ports are equal, so as to realize deflection of beam angles. When different input ports are fed, the phase difference of adjacent output ports is different, so that deflection of different angles of the wave beam can be realized through different input port feeds, and fig. 2 and 3 respectively show a schematic diagram of a 4×4 barrett matrix and a schematic diagram of a wave beam radiation angle.
The number of input ports and output ports of the barrett matrix determines the range of the offset angle of the barrett matrix to the beam, and one of the input ports of the barrett matrix is selected as a target input port for inputting the synthesized transmission signal during each transmission. As shown in fig. 4, the four-way transmission channel transmits an equal-power transmission signal to the power combiner 401, the power combiner 401 performs power combining and then transmits the combined transmission signal to the selection switch 402, and the selection switch 402 selects one of the input ports of one of the barrett matrixes 403 as a target input port to input the combined transmission signal.
Step S102: and controlling the Bullet matrix to transmit target beam signals through at least two paths of transmitting antennas, wherein the transmission angle range of the target beam signals is the target coverage angle range corresponding to the target input port.
The Basler matrix receives the synthesized transmitting signals, and transmits target beam signals from all paths of transmitting antennas, wherein the target beam signals are beam signals subjected to angle offset, and the transmitting angle range is a target coverage angle range corresponding to a target input port. For a 4 x 4 barrert matrix, the target input port is port 1 'in fig. 2, then the target coverage angle is lobe 1' in fig. 3; the target input port is port 2 'in fig. 2, then the target coverage angle is lobe 2' in fig. 3; the target input port is port 3 'in fig. 2, then the target coverage angle is lobe 3' in fig. 3; the target input port is port 4 'in fig. 2, then the target coverage angle is lobe 4' in fig. 3.
Step S103: the radar receiving end is controlled to receive a target echo wave beam within a target coverage angle range.
The radar receiving end comprises a plurality of receiving antennas, and all the receiving antennas simultaneously receive target echo beams of which the targets cover an angle range during receiving.
Step S104: and carrying out target detection analysis on the target echo wave beam to obtain detection information corresponding to the target coverage angle range.
The target echo wave beam can be converted into a digital wave beam, and target detection analysis is carried out on the digital wave beam, so that detection information corresponding to the target coverage angle range can be obtained. The target detection analysis may employ a target detection analysis method in the prior art, such as a frequency conversion-MTI-MTD-CFAR-target detection procedure.
In the embodiment of the application, the target input end of the composite transmitting signal input barrett matrix is generated, the barrett matrix transmits the target beam signals deflected by the angles through at least two paths of antennas, and different target input ends have different target coverage angles, so that the composite transmitting power can realize long-distance detection, and larger angles can be covered by inputting different input ends of the barrett matrix.
In one embodiment, the barrett matrix comprises at least two input ports;
the remote radar detection method further comprises the following steps:
and sequentially selecting one of the input ports as a target input port according to a preset sequence, and circularly executing the single detection step.
Specifically, each input port of the barrett matrix corresponds to different target coverage areas, and when long-range radar detection is performed, each input port is sequentially selected as a target input port according to a preset sequence, so that target detection in all angle coverage areas of the barrett matrix can be realized.
The preset sequence may be ordered according to the size relation of the corresponding target coverage, taking a 4×4 barrert matrix as an example, the target coverage angle ranges corresponding to the four input ports 1', 2', 3', 4' are sequentially-60 ° to-30 °, 30 ° to 0 °, 0 ° to 30 °, 30 ° to 60 °, and then the preset sequence may be set to 1', 2', 3', 4', so as to realize target detection of all airspaces within 120 ° from-60 ° to 60 °.
In one embodiment, controlling the barrett matrix to output the target beam signal specifically includes:
determining a target phase difference according to the target input port;
and controlling the transmitting ends of the adjacent output ports to form a target phase difference, and transmitting target beam signals through all the output ports, so that the transmitting angle range of the target beam signals is the target coverage angle range corresponding to the target input port.
Specifically, for different input ports, the barrett matrix realizes the transmission angle of the transmission beam by adjusting the phase difference between the transmission ends of the adjacent output ports. The output port of the barrett matrix is provided with a transmitting antenna, namely, the transmitting angle of a transmitting beam is adjusted by adjusting the phase difference of adjacent transmitting antennas.
After receiving the synthesized transmission signals, determining a target phase difference according to the target input ports, and then controlling the transmission ends of the adjacent output ports to form the target phase difference, and transmitting target beam signals through the output ports at the moment, so that the transmission angle range of the target beam signals is a target coverage angle range.
Taking a 4×4 barrert matrix as an example, when the target input port is the input port 1', the target phase difference is 45 °, and the corresponding target coverage angle ranges are sequentially-60 ° to-30 °; when the target input port is the input port 2', the target phase difference is 135 degrees, and the corresponding target coverage angle ranges are sequentially-30 degrees to 0 degrees; when the target input port is an input port 3', the target phase difference is minus 135 degrees, and the corresponding target coverage angle ranges are 0-30 degrees in sequence; when the target input port is input port 4', the target phase difference is-45 degrees, and the corresponding target coverage angle ranges are 30 degrees to 60 degrees in sequence.
In one embodiment, the controlling the radar receiving end receives a target echo beam within a target coverage angle range, specifically includes:
controlling each path of receiving antenna of the radar receiving end to receive the target echo signal;
converting a target echo signal into a digital echo signal in each path of receiving channel, wherein each path of receiving antenna corresponds to one path of receiving channel;
and carrying out phase weighting on the digital echo signals of all the receiving channels according to the target coverage angle range to generate a target echo wave beam.
Specifically, each time a target echo signal is received, all receiving antennas at the radar receiving end simultaneously receive the target echo signal, and then each path of echo signal is subjected to AD sampling in a corresponding receiving channel, and converted into a digital echo signal. And then carrying out phase weighting on all the digital echo signals according to the target coverage angle range to generate a target echo wave beam: and acquiring a target phase difference corresponding to the target coverage angle, and carrying out phase weighting on all digital echo signals according to the target phase difference and the number of target echo beams so as to generate the target echo beams.
Wherein the target echo beam comprises at least two digital beams, and the sum of the coverage areas of all the digital beams is equal to the target coverage angle. The larger the coverage of a single digital beam is, the smaller the detection distance is, and in order to improve the echo detection distance, a plurality of digital beams are arranged for a target echo signal in a target coverage angle range, and the sum of the coverage of all the digital beams is equal to the target coverage angle.
For a 4 x 4 barrert matrix, each target covers an angular range of 30 ° and the target echo beam comprises four digital beams, each having a coverage of 7.5 °.
The more the number of receiving antennas at the radar receiving end is, the smaller the coverage area of each digital beam is, and for this purpose, the number of receiving antennas at the radar receiving end can be determined according to the coverage area of each digital beam. When the coverage area of the digital beam is 7.5 degrees, the number of the receiving antennas is 16, and the structure of the radar receiving end is shown in fig. 5.
According to the embodiment of the application, a digital beam forming technology is adopted at a radar receiving end, a plurality of digital beams are generated to follow target beam signals, the coverage angle range of the target beam signals is covered, a certain angle resolution is achieved, and the influence of strong interference outside the beams is eliminated.
