摘　　要：同时全极化雷达是面向空中运动目标动态散射矩阵测量的一种全极化雷达,针对同时全极化雷达系统特点,对同时全极化雷达系统中匹配滤波器引入的误差进行了分析,并仿照分时全极化雷达系统模型的发射和接收失真矩阵模型,给出了匹配滤波器引入的失真矩阵及各矩阵元素的物理意义。分析了目标运动估计对目标动态散射矩阵测量的影响机理,提出了运动估计误差矩阵,利用该矩阵对同时全极化雷达测量影响进行了定量仿真分析,从而为同时全极化雷达系统运动估计方法的性能要求提供理论依据。Simultaneous polarimetric radar is a kind of radar which is used to measure the dynamic scattering matrix for air moving targets.In this paper,we analyze the error that is introduced by the matching filter according to the characteristic of simultaneous full polarimetric radar.Refer to the system model of traditional time alternate full polarimetric radar,we define the matched filter matrix and explain the meaning of each elements of the matrix.The influence of moving parameters estimation on the measurement is analyzed.The error of the estimated moving parameters matrix is proposed and quantitative analysis is given through simulation.The simulation analysis provides a theoretical basis for the performance requirements of a polarimetric radar motion estimation method.
