外辐射源雷达参考通道多径干扰抑制方法
Method for multipath interference restraint of the reference channel in passive bistatic radar
摘要
Abstract
Aiming at the fact that the reference channel includes the multipath interference in the passive bistatic radar,this paper proposes a method to restrain the multipath interference in the reference channel based on the modified constant modulus algorithm.The multipath interference in the reference channel will impact the following interference removing and matched filtering.Because of the strong relativity of the multipath interference with the direct-path signal,the traditional method cannot remove the multipath interference effectively.According to the constant modulus feature of the opportunity illuminator signal, this method utilizes the modified constant modulus algorithm to blind equalize the reference signal and restrain the multipath interference without any training sequence.Compared with the traditional blind equalization method,the method proposed in this paper owns the steadier convergence and the better performance of multipath interference restraint.Simulation prove the availability of the method proposed in this paper.关键词
