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 multi-frequency point phase distribution method for radar antenna array elements. The multi-frequency point phase distribution method comprises the following steps: S1, connecting a test probe into an appointed antenna array element; S2, sending control information corresponding to a frequency point of the appointed antenna array element to an array plane control source by a control computer; S3, measuring data corresponding to the frequency point by using a vector network analyzer, and transmitting the data to the control computer through a GPIB (general purpose interface bus) cable; S4, storing the data in a corresponding database after the data under the frequency point is received by the control computer and corresponding data processing is performed; S5, judging whether the phase distribution of all the frequency points of one array element is finished or not; S6, judging whether the phase distribution of all the frequency points of all the array elements is finished or not. The plug time of each frequency point is greatly reduced, so the plug time of a whole phase distribution cycle is further shortened, manpower, material resources and financial resources in the phase distribution process are saved, and the development cycle and the production cycle are greatly shortened.

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...
