Abstract

The invention provides a method for testing an aiming error of a radome, and belongs to the technical field of electromagnetic fields and microwaves. According to the method, equi-scale scanning of atraditional zero-searching device is improved into variable-scale scanning, namely, a zero depth position is positioned coarsely via a relatively wide scanning range and a relatively low scanning precision to obtain only a coarse position of the zero depth, further, the scanning range is narrowed and the precision is improved, the number of sampling points is reduced greatly, and the efficiency intesting the aiming error of the radome can be improved greatly. Thus, the traditional equi-scale scanning manner for testing the aiming error of the radome is changed, the difficulty of low testing efficiency of the aiming error is overcome, and the test method has good engineering and application prospects.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic fields and microwaves, and in particular relates to a test method for aiming error of a radome. Background technique [0002] The aiming error test is an item of the radome electrical performance test. The test methods include the zero search method and the amplitude electronic calibration method. Among them, the electronic calibration method test system needs to establish a calibration curve between the receiving level and the aiming error. For the new The developed radome often needs to re-establish the calibration curve, so there are certain deficiencies. Compared with the electronic calibration method, the zero search method is closer to the actual working state of the radome. It is realized by the mobile scanning of the transmitting antenna or the small-scale rotational scanning of the receiving antenna The positioning of the antenna beam pointing, the test is more accurate, but the t...
