Polarization radar target recognition based on optimal curve fitting

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.
