摘　　要：针对非合作无源相干定位中强直达波与多径杂波对目标散射信号的强抑制特点,提出了采用AR与MA的混合模型消除直达波与多径杂波的新方法。文中推导了采用AR模型和MA模型对多径信道建模的正则方程,提出了采用混合模型消除直达波与杂波的迭代算法。理论与仿真结果表明该方法对直达波与多径杂波的消除是非常有效的。It is a problem in non-cooperate passive location system that strong direct signal and muhipath clutter strongly reject the object echoes.Therefore,a novel method of clutter cancellation based on AR and MA mixed model is proposed to solve this problem.In this paper the regular equations of AR and MA models built for multipath channels are derived,and an iterative algorithm of direct signal and multipath clutter cancellation is proposed.Theoretical and simulated results show that this method is very effectiv...
