A method of separating target from cluster by polarization in unknown and time-varying circumstance

This paper discusses a method of recognizing target from unknown and time-varying cluster in polarization domain, by receiving from both vertical and azimuth channel of full polarization radar. First, the principle of the cluster removing algorithm, the determination of original parameter and calculating step are presented. Then, the signal after being removed cluster is simulated, and the result justifies the affectivity of the algorithm. In the end, the polarization characteristic of target is gained from the echo wave, and in further the recursive algorithm is proposed, which is confirmed by simulation.
