摘要:
随着军事电子技术的不断发展,雷达干扰和抗干扰的斗争愈演愈烈。为研究无源干扰条件下双基地雷达的作战效能问题,采用定量方法从双基地雷达方程与箔条干扰原理出发,分析了双基地雷达在有无箔条干扰下的探测能力,推导了收发天线不同极化方式下箔条截面积的精确表达式,提出了箔条干扰下的目标探测判决式,然后在区域网格剖分搜索算法的基础上定义了探测区面积的计算方法,最后对无源箔条干扰下双基地雷达的干扰暴露区进行了仿真,并得出了干扰暴露区面积。

Abstract:
With the continuous development of military electronic technology,the struggle between radar jamming and anti-jamming is becoming more and more intense. In order to study the combat effectiveness of bistatic radar under passive jamming,the quantitative method is used to analyze the detection ability of bistatic radar under chaff interference from bistatic radar equation and chaff interference principle. The exact expression of chaff section area under different polarization modes is derived,and the foil is proposed. On the basis of the regional grid subdivision search algorithm,the calculation method of the area of the detection region is defined. Finally,the jamming exposure region of the bistatic radar under the passive chaff is simulated,and the area of the jamming exposure region is obtained.
Key words:  passive jamming  bistatic radar  chaff jamming  search coverage  radar anti-jamming
