Abstract: The iterative-filtering formula of APC is derived in this paper. The convergence performances of the closed-loop scheme are analysised, and the preprocess method for enhancing convergence rate is proposed. The concept of polarization gain map is proposed. For the case of more Jammers with different polarizations, the performance of APC and full-adaptive polarizatioin array are analysised and compared. Finally, the simulation on the computer validates the scheme and conclusions in the paper. -
