Abstract:

In view of the problem of radar anti-jamming performance evaluation, a method of radar anti-jamming performance evaluation based on grey correlation fuzzy comprehensive evaluation is proposed. Based on the theory of fuzzy mathematics and correlation function, the set of fuzzy comprehensive evaluation factors of the evaluation index for reference is used firstly. Through scoring by the interval number, the weight of the evaluation index is determined based on the grey correlation method. Then, the fuzzy comprehensive evaluation results are calculated by establishing the evaluation matrix by the membership function, and the anti-jamming capability level of radar is determined according to the membership degree. Finally, the fuzzy value linear order evaluation model is established to determine the order of radar anti-jamming performance. The example shows that the proposed method can not only determine the evaluation level of radar anti-jamming performance, but also further determine the order of radar anti-jamming performance, which is more objective and reliable.

Key words: radar anti-jamming, fuzzy comprehensive evaluation, grey correlation, linear order method
