| 摘要: |
| 针对全极化测量体制雷达，研究了有源诱饵等欺骗性电子干扰的鉴别问题。首先详细分析了干扰机天线为圆极化和线极化两种典型情况下有源诱饵的极化特性，探讨了雷达目标的极化散射特性；而后提出了能够有效表征有源诱饵和雷达目标极化特性之间差异的参量——共交极化比及其峰值、聚类中心等概念和定义，并设计了有源诱饵的极化鉴别算法；最后，结合实测数据，计算机仿真实验表明鉴别算法的可行性和有效性。 |

| Abstract: |
| The discrimination problem of the active decoy and radar target is studied based on the full polarization measurement radar system in. Firstly, the polarization characteristic of the active decoy is analyzed under the condition of which antenna polarizations are circular polarization and linear polarization. Then, some polarization scattering properties of the radar target are also discussed. The co-polarization and cross-polarization ratio and its characteristics are presented, which can effectively of the polarization characteristic difference between the active decoy and radar target. A novel polarization discrimination proposal of the active decoy and radar target is given. Finally，the feasibility and validity of the discrimination proposal are verified by computer simulation and actual measured data. |
