摘　　要：采用多点源诱偏技术是雷达对抗反辐射导弹(anti-radiation missile,ARM)攻击的一种有效方法。针对抗非相干三点源诱偏的问题,建立了干涉仪体制反辐射导引头测向模型,分析了在非相干三点源作用下干涉仪体制反辐射导引头的角度输出特性,并指出在三点源信号幅度满足一定条件的前提下,通过一定数量脉冲积累能使导引头指向大功率源。理论分析和数值仿真结果验证了分析的正确性。Multi-decoy misguiding is an effective technique in counteracting anti-radiation missiles（ARMs）.This paper addresses the problem of anti-decoying three uncorrelated decoys with interferometer-based passive radar seekers（PRSs）.The property of the angular measurements of the PRS is analyzed to conclude that,accumulated data guides the PRS towards the source with largest power when certain preconditions are satisfied.Theoretical analysis and simulation results are carried out to demonstrate the conclusions.
