Improved LMS Algorithm and Its Application in Direct Path and Multipath Cancellation for Passive Radar

摘要：

　　In passive radar,the targets echo could be masked by the sidelobes of the direct path and multipath interference (DPI and MPI) received by the receiver antenna.So the direct path and multipath interference cancellation is a key factor in passive radar systems.In this paper,an improved LMS algorithm is proposed,and its performance in passive radar direct path and multipath interference cancellation is analyzed.The proposed algorithm,which varies the step size,has better performance compared with the traditional LMS filter.The computer simulation results show that the algorithm has a faster convergence rate and a smaller steady state error.
