摘　　要：研究了有源多假目标等欺骗性电子干扰对地基防御雷达系统的有效性问题。首先详细分析了任一椭圆极化天线有源假目标的极化特性,并探讨了典型雷达目标的极化散射特性。在此基础上,设计了有源多假目标的极化鉴别算法,计算机仿真表明,具有极化测量能力的地基防御雷达系统具有对有源多假目标进行鉴别的能力。The validity problem of active multi-decoy to ground base radar system is studied. Firstly, the polarization characteristics of active multi-decoy of any elliptic polarized antenna jammer are presented and the polarization scattering properties of radar target are also discussed. Then, a novel polarization discrimination algorithm of active multi-decoy and radar target is designed and computer simulations indicated that ground-base radar system is possessed of the discriminatory ability of active multi-decoy and radar target.
