weed suppression

Traditional clutter rejection methods such as FIR,IIR and regression filters are based on the hypothesis that the clutter signal is stationary.

传统的杂波抑制器如有限脉冲响应(FIR)、无限脉冲响应(IIR)和回归型滤波器,都是针对平稳杂波信号抑制的。

The technique of adaptive clutter rejection in clutter environment is discussed.

研究雷达在杂波环境下的自适应杂波抑制技术,介绍了参差时变多凹口滤波器设计方法,给出了一种带通滤波器实现方法,从而说明全频道杂波轮廓图的工作原理,利用杂波轮廓图信息确定杂波所在的多普勒频率范围,以此选择相应频道的MTI滤波器,实现AMTI,事实已证明该技术的可行性。

First of all,the ordinary adaptive MTI techniques in radar signal processing are discussed,the approach to adaptiveclutter rejection in multiclutter environment is analyzed in this paper.
