干扰位置可控的SAR散射波干扰方法

A SAR Scatter⁃Wave Jamming Method with Controllable Jamming Position

当前对SAR的散射波干扰产生的虚假图像位置较为固定,且受侦察参数误差和环境影响会出现一定偏移,难以准确覆盖在目标区域之上,针对这一难题,本文提出了一种对SAR的散射波干扰进行位置调制,产生位置可控的假目标的方法,此方法结合SAR成像的距离向和方位向两个维度的位置参数进行调制,实验结果表明,与传统对SAR的散射波干扰相比,本文方法产生的干扰图像可以精准覆盖在目标区域之上,使雷达端的成像结果中对真实目标和干扰图像的识别结果被混淆。

At present,the position of false images generated by the scatter⁃wave jamming of SAR is relatively fixed,and there will be a certain deviation due to reconnaissance parameter errors and environmental influences,making it difficult to accurately cover the target area.In order to solve this problem,this paper proposes a method for modulating the position of scatter⁃wave jamming of SAR to generate controllable false targets.This method combines the position pa⁃rameters of the distance and azimuth dimensions of SAR imaging for modulation.The experimental results show that compared with the traditional SAR scatter⁃wave jamming,the interference images generated by this method can accu⁃rately cover the target area,causing confusion in the recognition results of real targets and interference images in the ra⁃dar imaging results.
