对极化雷达的有源干扰研究

Study of the active jamming on polarimetric radars

针对分时极化测量雷达,设计了一种全极化欺骗干扰方法,并分析了有源假目标的极化特性。对全极化有源假目标和雷达目标的分析结果表明,提出的欺骗干扰方法形成的假目标的散射矩阵、Graves功率矩阵以及极化特征描述子矢量等参数与雷达目标具有很强的相似性,它可以有效地干扰极化测量雷达。

A lull polarization active jamming method is proposed. The scattering matrix, Graves matrix and polarization characteristic vector of the false targets produced by the full polarization jammer are analysed. It is shown that these parameters are more similar to the radar targets than those of the single polarization active jammer. The simulations show that the jamming method proposed can effectively jams the polarimetrie radars.
