基于SSC的星载SAR有源干扰方法

Research on spaceborne active jamming on SSC

不同干扰方式对星载SAR的干扰效果主要取决于干扰信号与SAR回波信号的相似度,即干扰信号在信号结构和特征方面与星载SAR回波的相似程度。通过提出一种基于散射统计特性(SSC)的星载SAR有源干扰方法,构建用于干扰星载SAR的类杂波信号数学模型,分析该信号与星载SAR回波信号的散射统计特性相似度,并进行了仿真分析。仿真结果表明该方法在相同的干信比下有更好的干扰效果,具有较好的应用前景。

In whichever jamming mode, the jamming effect of spaceborne SAR mainly lies on the similarity between jamming signal and spaceborne SAR echo, namely signal structure and character of similarity between the two. In this paper, an active jamming method for spaceborne SAR based on the scattering statistical characteristics(SSC) is proposed. The mathematical mode of clutter-like signal used for jamming spaceborne SAR is constructed, the scattering statistics characteristic similarity between spaceborne SAR echo and this jamming signal is analyzed and simulated. Results show that this method has a better interference effect under the same jamming signal ratio and a better application prospect.
