基于图信号处理的频控阵MIMO雷达动目标检测方法
FDA-MIMO radar moving target detection method based on graph signal processing
摘要
Abstract
Under the background of complex signals,FDA-MIMO radars are subjected to interference from clutter and noise sources,which greatly degrades their detection performance for dim targets.To cope with this challenge,a graph signal processing(GSP)based moving target detection method for FDA-MIMO is proposed.Firstly,the phase variation of Doppler frequency shift term is eliminated with MTI/MTD technique,and then the graph signal model based on FDA-MIMO is constructed,and the spectral peak search response function is established with the graph Fourier transform(GFT)of the echo signals,which finally achieves the three-dimensional joint estimation of Doppler-range-angle parameters for the moving targets.The simulation results verify that the proposed method is able to estimate the parameter information of the target more accurately in comparison with the classical MUSIC(multiple signal classification)algorithm under the complex signal environment,so the method improves the detection performance of dim targets effectively.关键词
