火控雷达抗压制性干扰指标及其相关性分析

火控雷达抗有源压制性干扰的性能评估是现代雷达性能评估的一个重要方面。作为雷达抗干扰性能评估的基础,抗干扰指标从根本上决定了评估工作的有效性和可靠性。首先介绍了有源压制性干扰的作用特点,分析总结了抗压制性干扰的指标集;然后通过理论计算与公式推导的方法,验证了抗压制性干扰指标间存在着等效性与可替代性的特点,获取了完备性好、可测性高的基础指标;在此基础上提出了以“自卫距离”和“可见度因子”两个指标来度量火控雷达的整体抗压制性干扰性能的评估思路,大大降低了性能评估实验的组织实施成本和复杂度,为火控雷达抗干扰性能评估奠定了基础,对靶场试验也具有一定的指导意义。

Index and its correlation analysis of fire-control radar anti-jamming ability against active blanketing jamming

The evaluation of fire-control radar anti-jamming effectiveness is an important aspect of the comprehensive combat performance. As the basis of radar anti-jamming evaluation performance,the indexes determine the validity and reliability of assessment methods fundamentally. In this paper,the characteristics of active blanket jamming are introduced,and the index set of anti-jamming performance is summarized. Then theoretical calculation and derivations of formulas are given to verify that equivalence and substitutability exists in the anti-jamming indexes,and get an integrated and fathomable index. On this basis,a test method of radar anti-jamming evaluation which contains "self-defense distance" and "visibility factor" indicators to measure fire-control radar anti-jamming performance is advanced. The method greatly reduces the implementation costs and complexity of the performance evaluation test,and lays the foundation for fire-control radar anti-jamming performance assessment. The assessment method can also provide guidance for range test.
