Description

Technical Field

[0001] This invention relates to the field of phased array development technology, and in particular to a phased array antenna test platform, design method, and computer-readable storage medium. Background Technology

[0002] A phased array antenna is an antenna that changes its radiation pattern shape by controlling the feed phase of the radiating elements in the array. Controlling the phase can change the direction of the antenna's maximum radiation value to achieve beam scanning. In special cases, it can also control the sidelobe level, the minimum position, and the overall shape of the radiation pattern, such as obtaining a cosecting square radiation pattern and performing adaptive control of the radiation pattern.

[0003] When rotating an antenna mechanically, the inertia is large and the speed is slow. Phased array antennas overcome this drawback, achieving high beam scanning speed. Their feed phase is typically controlled by a computer, resulting in rapid phase changes (on the order of milliseconds), meaning the maximum value of the antenna pattern or other parameters changes rapidly. This is the most significant characteristic of phased array antennas.

Figure 2 This is a flowchart for the debugging and testing of existing phased array antennas, provided by... Figure 2 It is known that the existing phased array antenna debugging and testing process requires redesigning the FPGA program and conducting secondary testing after a test problem is discovered, which seriously affects the debugging and testing efficiency.

[0038] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0039] Please see Figures 3-6 As shown, the phased array antenna test platform design method of this embodiment is used to test a phased array antenna. The phased array antenna includes a beam controller and a TR component. The TR component includes a first control interface and a second control interface. The first control interface is communicatively connected to the beam controller, and the second control interface is communicatively connected to a control board. The control board can read the parameters of the TR component through the second control interface, so that the reading process of the TR component parameters can be carried out without going through the beam controller.

[0040] As is understandable, a TR component is a transceiver component; TR is an abbreviation for Transmitter and Receiver. Generally speaking, a TR component refers to the part between the video signal and the antenna in a wireless transceiver system. A wireless transceiver system is formed by connecting one end of the TR component to the antenna and the other end to the intermediate frequency processing unit. Its function is to amplify, phase-shift, and attenuate the signal. A TR component typically includes two branches: transmit and receive. The unit circuit should include: local oscillator, up / down converter, filter, low-noise amplifier, power amplifier, duplex circuit, etc. This invention designs the TR component with two control interfaces to communicate with the beam controller and control board respectively, so as to realize independent control of the TR component by the beam controller and control board.

[0044] S3. Generate a set of phased array antenna state matrices corresponding to the phased array antenna target matrix;

[0045] The parameters of the phased array antenna state matrix can be written to the TR component through the second control interface, and the parameters of the phased array antenna digital model can be updated according to the new TR component. The control board can also write the adjusted parameters of the phased array antenna digital model to the TR component through the second control interface.

[0046] It is understood that the parameters of the phased array antenna state matrix can be written to the TR component through the second control interface, and the parameters of the phased array antenna digital model can be updated according to the new TR component. The writing and updating processes do not need to go through the beam controller, so the testing process does not require modification of the beam controller program.

[0047] Preferably, the control board can generate a phased array antenna state matrix by back-mapping the parameters of the TR component through the array manifold.

[0048] Preferably, the parameters of the digital model of the phased array antenna include operating frequency, beam scanning parameters, array manifold data, calibration data, and operating status.

[0049] It is understood that the phased array antenna digital model can be designed using one set of phased array antenna digital model parameters or multiple sets of phased array antenna digital model parameters.

[0050] Preferably, each set of data in the phased array antenna target matrix includes amplitude and phase information for each TR channel. Of course, it may also include parameters such as power and temperature information for each TR channel.

[0051] Preferably, the phased array antenna test platform design method further includes:

[0052] The phased array antenna is controlled by the beam controller.

[0053] The target matrix of the phased array antenna and the state matrix of the phased array antenna generated by reverse mapping are compared to obtain a set of difference data;

[0054] The calculation errors of the beam controller are fed back based on the difference data.

[0055] Preferably, the phased array antenna test platform design method further includes:

[0056] The calibration data is used as input parameters of the digital model of the phased array antenna to obtain the loading information of the digital model of the phased array antenna with respect to the calibration data, and the calibration data is written into the beam controller through the control board to obtain the loading information of the beam controller with respect to the calibration data.

[0057] The loading information of the phased array antenna digital model with respect to the calibration data is compared with the loading information of the beam controller with respect to the calibration data to verify whether the loading of the beam controller with respect to the calibration data is correct.

[0058] Preferably, the phased array antenna test platform design method further includes:

[0059] The calibration data is used as the input parameters for the digital model of the phased array antenna;

[0060] The TR component can be directly controlled by the control board to calibrate the phased array antenna, thus eliminating the need for the beam controller to program the calibration function and effectively saving development costs.

[0061] Accordingly, please refer to Figure 7 As shown, this invention also discloses a phased array antenna test platform for testing phased array antennas. The phased array antenna includes a beam controller and a TR component. The TR component includes a first control interface and a second control interface. The first control interface is communicatively connected to the beam controller, and the second control interface is communicatively connected to a control board. The control board can read the parameters of the TR component through the second control interface. The phased array antenna test platform includes:

[0062] Construction unit 10 is configured to construct a digital model of the phased array antenna for the phased array antenna;

[0063] The first generation unit 20 is configured to generate a set of phased array antenna target matrices based on the phased array antenna digital model.

[0064] The second generation unit 30 is configured to generate a set of phased array antenna state matrices corresponding to the phased array antenna target matrix.

[0065] The parameters of the phased array antenna state matrix can be written to the TR component through the second control interface, and the parameters of the phased array antenna digital model can be updated according to the new TR component. The control board can also write the adjusted parameters of the phased array antenna digital model to the TR component through the second control interface.

[0066] Accordingly, the present invention also discloses a computer-readable storage medium for storing a computer program, which, when executed by a processor, implements the phased array antenna test platform design method described above.
