摘　　要：在建立极化空时信号模型的基础上,对全维空时自适应处理(STAP)的输出信杂噪比的计算式进行了分析,对比了该情况下极化空时自适应处理与STAP的性能,并指出了影响极化空时自适应处理性能的几个主要因素.仿真结果验证了分析结论的正确性.By the utilization of the additional polarized information, the minimum detectable velocity could be improved for space time adaptive processing under the polarimetric radar system. In this paper, the performance of polarization space time adaptive processing is analyzed and compared with the traditional space-time adaptive processing based on the output signal to clutter plus noise ratio, and the primary affecting factors of three dimensional processing are indicated. A preliminary result against an airborne simulation data verifies the conclusion.
