摘要: 該文推導(dǎo)得到了自適應(yīng)極化對(duì)消器(APC)的迭代濾波公式；分析了該閉環(huán)算法的收斂性能，并提出了加快收斂速度的預(yù)處理方法；引入了極化增益圖的概念，比較了多個(gè)極化干擾同時(shí)存在情況下，APC與全自適應(yīng)極化濾波器的性能；最后，仿真實(shí)驗(yàn)驗(yàn)證了該算法及文中結(jié)論的正確性。

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. -
