GSM信号外辐射源雷达同频干扰抑制方法
Method of co-channel interference cancellation for the GSM based PBR
摘要
Abstract
In passive bistatic radar,especially in the global system for mobile communication based passive bistatic radar,there are not only strong direct signal and multipath,but also co-channel interference.It is difficult to suppress co-channel interference using temporal adaptive cancellation without the samples of interference.Aiming at the problem of co-channel interference signals existing in the echo channel,a method of co-channel interference cancellation for passive bistatic radar is proposed.First,low sidelobe spatial filtering is used to remove the remote weak interference,at the same time the strong interference is suppressed to a certain extent.Then,the direct signal and multipath signal coming from the main station are suppressed by using temporal adaptive cancellation.Finally,the remaining interference is further cancelled by a robust adaptive beamformer.The performance and calculation of the proposed method are verified by theoretical analysis and simulation.关键词
