摘　　要：从比相单脉冲测向体制出发,推导出比相体制PRS跟踪相干两点源的数学模型,对两点源诱偏下被动雷达导引头的测角性能进行了分析,指出比相体制导引头无法分辨雷达和相干源诱饵,PRS将跟踪雷达和诱饵的合成相位中心,跟踪角度不固定且不断变化。仿真结果和实测数据均验证了结论的正确性。From the phase comparison angle measurement principle in monopulse PRS, the angle measurement mathematical model of phase comparison PRS tracing coherent dual sources is proposed, the PRS angle measurement performance with decoy of coherent source is analyzed. It shows that the phase-comparison PRS cannt distinguish radar and coherent decoy, PRS would trace the synthetical phase center of radar and decoy, the tracing angle is uncertain and changed continually. Both the simulation result and the experimental data con firm the correctness of the theory
