摘　　要：对映体干扰是一种在作战飞机上使用的雷达有源角度欺骗干扰方式。针对机载对映体干扰的应用方式,首先分析了机载对映体干扰的基本原理,然后计算了机载对映体干扰的有效作用区域,并且推导了机载对映体干扰实现有效干扰的基本条件,最后通过实验仿真定量地分析了干扰信号入射角、干扰信号波束宽度、干扰信号与雷达间距、干扰信号与雷达波束夹角以及地面反射特性等因素对映体干扰有效作用区域和干扰效果的影响。研究结果可以为机载对映体干扰的使用提供理论参考。The image-jamming is one of radar active jamming styles. In view of the applications of airborne image-jamming, the basic principle of the image-jamming is analyzed. The effective area and the effective jamming conditions of image-jamming are then discussed. In the end, by simulation experiment, the influences of ineident angle, beam width, distance between interference signal and radar, angle between interference signal and radar beam, ground reflection characteristics on the effective jamming area and the jamming effectiveness are analyzed. The research results could provide a theoretical reference for the use of the image-jamming style.
