摘要

基于乘积调制干扰理论

提出了一种新型逆合成孔径雷达欺骗干扰方法:对干扰模板图像作二维FFT(Fast Fourier Transform)变换从而离线快速生成干扰信号

再经过信号相乘调制到截获雷达信号上后转发

可在ISAR(Inverse Synthetic Aperture Radar)上形成虚假目标且假目标尺度可灵活缩放.在介绍乘积调制干扰的基本原理后

从理论上分析了ISAR假目标生成方法.在此基础上

研究了关键干扰参数对干扰效果的影响

给出了影响尺度缩放功能的关键因素和对侦察的依赖程度

最后进行了仿真验证

结果证明了该方法的可行性和有效性.

Abstract

A novel generation method of ISAR (Inverse Synthetic Aperture Radar)decoy is presented based on coherent multiplication modulated jamming.By processing the modal image by 2-D FFT(Fast Fourier Transform)

jamming signal can be formed offline and then modulated on interceptive radar signal to generate a vivid decoy with arbitrary shape and size.After the theory of coherent multiplication modulated jamming is expounded

a theoretical study is carried out to analyze this generation method.On this basis

more analyses are given the jamming parameters

and the key factor of scale zoom and the reliance on reconnaissance is presented.At last

the simulation demonstrates that the above method is feasible and effective.
