Research on the Test Technology of Electronic Countermeasures Equipment Direction Measurement

In response to the actual requirements of the direction finding test of the electronic countermeasures equipment, this paper establishes the direction finding model of the interferometer, the direction finding defuzzification algorithm, and analyzes the direction finding error of the interferometer. The model and algorithm were verified by simulation, and the main indicators were clarified in combination with actual equipment tests. An orthogonal test method was designed. The test was carried out with the direction finding range, test frequency, and signal-to-noise ratio direction finding baseline as factors, which reduced the number of tests. Obtain valid test results. It can provide technical support for the test and appraisal of electronic countermeasures equipment.
