Abstract: In the complex electromagnetic environment, how to measure radar anti-jamming performance effectively is not only the basis of radar electronic warfare dynamic simulation analysis, force planning and equipment demonstration, but also the problem to be solved urgently by radar equipment designers. To solve the problems of high test cost and difficult control of test conditions in radar anti-jamming performance evaluation index test and training support, an anti-jamming performance analysis and evaluation system is designed for the fire control radar. The basic principle of radar anti-jamming performance evaluation index measurement is analyzed, and the evaluation index measurement model is established. Combined with the hardware in loop simulation experiment, the test and evaluation method of anti-jamming performance is studied, which improves the disadvantages of the existing evaluation methods, establishes a set of realistic, open and expandable simulation system, realizes the analysis and evaluation of anti- jamming performance of fire control radar. It provides a meaningful technical way for the systematical study of radar anti-jamming performance evaluation.
