摘　　要：本文研究了一种SAR雷达平面目标欺骗干扰回波信号产生的方法。为了得到平面目标欺骗干扰的数学模型。首先总结了SAR雷达点目标回波的数学模型,进而推广到了平面目标回波的数学模型,利用该回波模型即可模拟生成平面目标欺骗干扰回波信号。在仿真实验中,通过对比SAR雷达原始回波信号的成像结果和叠加了平面目标欺骗干扰信号后的成像结果,明显地可以看出后者成像结果中存在欺骗干扰,验证了本文中平面目标欺骗干扰回波信号产生方法的正确性。In this paper,a method of generating deception jamming echo signal of SAR plane target is studied.In order to get the mathematical model of plane target deception jamming.Firstly,the mathematical model of SAR radar point target echo is summarized,and then it is extended to the mathematical model of plane target echo.Using this echo model,the deception jamming echo signal of plane target can be generated.In the simulation experiment,by comparing the imaging results of the original echo signal of SAR radar and the imaging results after superimposing the deception jamming signal of plane target,it is obvious that deception jamming exists in the imaging results of the latter,which verifies the correctness of the generation method of deception jamming echo signal of plane target in this paper.
