| 摘 要： | 以双接收站雷达为背景，研究了雷达目标和有源诱饵的鉴别方法。首先提出了双站极化散射矩阵和双站对角极化比的定义，探讨了雷达目标和有源诱饵的极化散射特性；然后针对极化调制有源诱饵等欺骗性干扰，提出了以双站对角极化比为鉴别量实现对有源诱饵鉴别的新方法，并设计了鉴别算法。对典型雷达目标和有源诱饵的仿真结果表明，该鉴别算法对有源诱饵的正确鉴别概率始终达到100%，对雷达目标的正确鉴别率也都能达到90%以上。仿真结果证明了该鉴别算法的可行性和有效性。

| Abstract: | The discrimination method of the radar target and the active decoy is studied based on the radar system with two receiving station. Firstly, the double-station polarization scattering matrix and the double-station diagonal polarization ratio are defined to study the polarization scattering properties of the radar target and the active decoy. Then, a discrimination method is proposed to discriminate the polarization-changed deceptive jamming by using the discriminate parameter of double-station diagonal polarization ratio. And the discrimination algorithm is also designed. Using the identification algorithm, the correct identification probability of active decoy is always 100%, and the correct identification probability of the radar target can also reach more than 90%. The effectiveness and the feasibility of the algorithm are proved by the simulation results. |
