多点源诱偏系统对抗反辐射导弹效能分析

基于有源诱偏系统对抗反辐射导弹(ARM,Anti-Radiation Missile)的理论,导出诱偏误差公式,以3种典型布局方案(三点源布局1、三点源布局2及四点源布局)为例,对误差公式进行简化处理,通过数值计算得到诱偏误差曲线,分析不同布局方案下辐射源功率比对诱偏误差的影响;同时分析ARM的实际攻击过程,引入ARM机动修正,通过仿真分析得到ARM落点图和雷达保护概率曲线,对比不同布局方案下的诱偏效果,结果表明四点源布局为最优方案,对研究多点源诱偏系统对抗ARM的作战效能具有指导意义.

Effectiveness analysis of multi-source decoying system against ARM

Based on the theory of active decoying system against anti-rediation missile(ARM), decoy error formula was derived. Three typical distributions, which were the first three-source distribution, the second three-source distribution and four-source distribution were discussed as examples, and the error formulae of them were simplified, and decoy error curves were obtained with numerical calculation, then the influence of radiation source power rate on decoy error under different distributions was analyzed. Besides, the real attack process of ARM was also analyzed, and ARM-s mobile correction was inducted. Then diagrams of ARM-s point of impact and radar-s protect probability curves were obtained with simulation analysis. Decoy effect of different distributions was compared with each other, and the results show that four-source distribution is the best plan. These conclusions have great significance in researching the operational effectiveness of multi-source decoying system against ARM.
