摘　　要：干涉仪由于可实现单脉冲测向,具有良好的抗单点有源干扰能力,但可通过实施两点源相干干扰来干扰其测向性能。首先介绍两点源对干涉仪实施相干干扰的基本原理,并对干扰效果进行数字仿真,详细分析了影响干扰效果的相关因素,最后对实施两点源相干干扰的限制条件进行了说明。While the one-source interference technique is ineffective to counteract interferometer because of its ability of monopulse direction finding,the coherent dual-source interference is effective.The basic principle of the coherent dual-source interference technique is introduced firstly.Then simulation results are presented,and factors related to jamming performace are analyzed.Finally,the conditions to realize this technique are given.
