一种末制导雷达有源干扰效果评估方法

A evaluation method for active jamming effect on terminal guidance radar

摘要:

为了实现对末制导雷达有源干扰效果精确定量的评估,根据末制导雷达的工作过程及其有源干扰的特点,提出以干扰前后雷达的搜索时间比和跟踪误差比作为评估干扰效果的两个指标,并分析了干扰前后雷达的搜索时间比、跟踪误差比们与影响因素之间的关系.根据评估指标与有效干扰的对应关系,对其进行了归一化处理,利用加权求和的方法得到综合的干扰结果.仿真试验结果表明,评估指标科学合理,便于测量,综合评估方法简单有效.

Abstract:

To accurately evaluate the jamming effect on terminal guidance radar under active jamming,according to the working process of terminal guidance radar and the characteristic of counteractive active jamming,the ratio of detecting-target-time and the ratio of tracing-error were adopted as indexes,and the relationship between indexes and influence factors and the evaluation methods were analyzed briefly.The indexes were treated by unitary quantification and weighted summation to get the synthetic results.The simulation results show that the evaluation indexes are scientific and easy to be measured,and the evaluation method is simple and effective.
