摘　　要：相干两点源能够对单脉冲体制雷达产生角度欺骗的干扰效果,交叉眼作为相干两点源典型的可行应用形式,能够修正由于传输路径不同带来的两个干扰源信号相位差。文章在研究两点源干扰原理的基础上,通过建立数学模型,仿真计算,分析交叉眼系统中两个干扰点功率差和相位差的边界条件,旨在对工程设计提供一定参考。Coherent dualsources jamming system has the ability to affect the angle measurement of mono pulse radar. As a feasible application of coherent dualsources system, crosseye interference can amend the phasedifference of the tow sources, caused by distancedifference. However, the powerdifference and the phasedifference of the two sources, caused by componentsdifference, will make the interference less effective or even ineffective. By simulating, this paper analyzes the impact to crosseye system, caused by powerdiffer ence and phasedifference, which can make some reference to design.
