摘要
Abstract
Clutter cancellation is a research focus in passive radar.The decorrelation effect deteriorates the performance of clutter cancellation.In single frequency network (SFN) mode,due to the decorrelation of signals from different transmitters,the clutter in echo signal cannot be effectively cancelled by the traditional clutter cancellation algorithms,leading to a serious declination in the performance of clutter cancellation.Through the analysis,this paper proposes a new clutter cancellation algorithm based on NLMS for passive radar in SFN.The theoretical analysis and simulationresults verify the performance of the improved algorithm.This paper provides a solution for the problem of signal decorrelation in SFN and also provides a theoretical guidance for passive radar in SFN.关键词
