摘　　要：针对目前多点源诱偏效果评估过程中,仅考虑各点源相位分量变化,未考虑幅度分量在空中变化的不足,基于雷达和诱饵的具体方向图,运用等相位面梯度分析法,同时考虑各点源辐射信号的相位和幅度波动的影响,对相参多诱饵系统的诱偏误差公式进行了推导。建立了诱饵系统的毁伤概率模型,并以相参三点源诱偏系统诱偏效果为例,分别对ARM从全方位来袭时的诱偏效果、从重点防御方向来袭时的诱偏效果以及三点源之间部署间隔变化对诱偏效果的影响进行了仿真分析。最终获得了一些对诱饵实际部署有指导性的结论。According to the shortage of only considering the phase change of emitter and no refer to the am plitude change, based on the patterns of radar and decoy, using equal phase gradient method, while considering the influence about waviness of phase and amplitude of each, the decoying formula of the coherent decoy system is deduced, a damage probability model is drawn out. Taking the decoying effect of three-emitter coherent decoy system as an instance, the decoying effect of while ARM raiding from all directions, or from keystone direction, and the deploy interval change of three-emitter is analyzed. Finally some instructive conclusions on decoy deploying are obtained.
