Embodiment

[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...

Abstract

The invention belongs to the field of microwave measurement, and relates to a method for multi-frequency point matching of radar antenna array elements, which includes the following steps: Step 1: Connect a test probe to a designated antenna array element; The source sends the control information corresponding to a frequency point of the specified antenna element; Step 3: Measure the data of the corresponding frequency point with a vector network analyzer, and transmit it to the control computer through the GPIB cable; Step 4: The control computer receives the data at this frequency point The data is stored in the corresponding database after corresponding data processing. Step 5: Judging whether the matching of all frequency points of an array element is completed; Step 6: Judging whether matching of all frequency points of all array elements is completed. The number of times of plugging and unplugging at each frequency point is greatly reduced, thereby reducing the plugging and unplugging time of the entire matching cycle, saving manpower, material resources, and financial resources in the matching process, and greatly shortening the development and production cycle.

Description

technical field [0001] The invention belongs to the field of microwave measurement and relates to a multi-frequency point matching method for radar antenna array elements. Background technique [0002] In the development and production process of the phased array radar antenna, it is necessary to carry out phase matching work for each array element in the radar antenna, so that each array element can work according to a certain working phase. In the phase matching process, for a certain characteristic frequency point, all the phase shifters complete a phase matching, which is called completing a phase matching cycle. Since the radar needs to work with multiple frequency points, it is necessary to perform multi-frequency point matching for all array elements in the front. However, in the traditional matching method, only one frequency point can be matched in one matching cycle, which leads to too long matching time and extremely low matching efficiency. [0003] From an eco...
