The Influence of Moving Parameters Deviation on Simultaneous Full Polarimetric Radar and Quantitative Analysis

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.
