摘　　要：相干两点源能够对单脉冲体制雷达形成有效的角度欺骗干扰,通过干扰机之间协同,达到诱偏雷达波束、掩护目标突防的目的.根据两点源角度欺骗干扰原理,利用相干两点源和雷达目标全极化回波特性差异,设计了识别相干两点源角度欺骗干扰识的二元假设检验方法,理论分析和仿真结果证实了方法的有效性.Coherent dual point sources are widely used in angular deception jamming for mono-pulse radar. With the cooperation of active jamming systems, radar beam of de- fence system can be effectively pulled off from target, and the aim of target penetration will be achieved. According to the principle of dual point sources angular jamming, fully polarization echoes of angular deception false targets formed by coherent dual point sources, is derived theoretically. Based on the difference of radar echoes of false target and physical targets, a novel binary hypothesis testing method for discriminating angu- lar deception false targets from others is presented. Theoretical analysis and simulations indicate that the method is valid and feasible.
