摘　　要：弹道目标的极化特性在弹道目标识别中呈现出极大的应用潜力。针对弹道目标的极化特性,着重分析弹道目标的极化相关性。基于一种弹道目标动态全极化回波仿真方法得到典型战情下的雷达回波,然后重点分析四类弹头目标的极化相关特性,得到了一组对雷达工程实践有意义的结论,对于弹道目标识别中分时极化测量雷达的数据率设置具有一定的工程参考价值。Polarization characteristics show great potential in the area of ballistic target recognition. Aiming at the polarization characteristics of ballistic target, polarization correlation characteristics is mainly analysed. The full-polarization radar echoes under typal battle situation are simulated based on data measured in anechoic chamber. Then the polarization correlation characteristics of a set of simulated ballistic targets are analysed. A group of conclusions, which are of meanings for radar engineering technology, are gained. There conclu- sion are valuable for the setting of pulse repetition interval of alternative polarization measurement radar.
