摘要:

结合极化信息可提高空时自适应处理(STAP)的慢速动目标检测性能,在级联处理结构下,为有效分析极化-空时级联处理(P-ST)和空时-极化级联处理(ST-P)的具体性能,推导了极化-空时联合处理与级联处理的自适应滤波权矢量形式,定量分析了P-ST和ST-P的检测性能与级联顺序、目标和杂波的极化区分度、空时区分度的关系,为选择合适的级联处理方法提供了依据.仿真结果有效验证了分析结论的正确性.

Abstract:

Polarization-SpaceTime or SpaceTime-Polarization cascade processing can detect low velocity moving targets with polarized information on the received signal. To make a detailed analysis of the cascade processing, the adaptive weight is deduced. Then the detection performance against the cascade order, the space-time division and polarization division between the signal and clutter are qualitatively analysised, which would provide an instruction for choosing an appropriate cascade processing order. Simulation verifies the correctness of the analyzed conclusion.

Key words: polarization radar, polarization space-time signal processing, cascade processing, adaptive processing, target detection
