Abstract :
In this paper, the conception of VOPS (Velocity of Polarization State) is presented to describe the dynamic characteristics of radar target´s polarization structure in the frequency domain an the polarimetric and high-resolution radar system. An improved simulated annealing method is presented to estimate the global optimal parameters of fitting curves of target´s dynamic distributions. Furthermore, recognition experiment has been made on four kinds of aircraft and good results are achieved
