[0023] Example: For 1000 array elements, each array element has 25 frequency points for matching.
[0024] A radar antenna array element multi-frequency point matching method, comprising the following steps:
[0025] Step 1: Connect the test probe to the designated antenna element;
[0026] Step 2: The control computer sends control information corresponding to a frequency point of the designated antenna element to the array control source, and the array control source generates an excitation signal for the designated antenna array element after receiving this information, and the corresponding antenna array element After receiving the excitation signal, the corresponding phase is generated;
[0027] Step 3: Use a vector network analyzer to measure the data of the corresponding frequency point, and transmit it to the control computer through the GPIB cable;
[0028] Step 4: The control computer receives the data at this frequency point and performs corresponding data process...
