分布式MIMO雷达目标散射模型研究
A Study on Target Scattering Model of Distributed MIMO Radar
摘要
Abstract
Aiming at the inadequacy of current research on target scattering model of distributed multiple-input multiple-output (MIMO) radar,a novel three-dimension target model with special shape is established in this paper.The formula for static radar cross-section (RCS) calculation and the correlation function of MIMO radar channels are deduced taking into consideration factors such as the electromagnetic scattering direction of point scatters,physical shielding,azimuth and pitch angle of transmitting and receiving antenna.The dynamic RCS distribution of the target and its relationship with bistatic angle between transmitting and receiving antenna are analyzed through numerical simulation.Besides,the conditions under which MIMO radar channels are uncorrelated are also analyzed.Simulation results conforms to the classical statistical models on RCS,the empirical conclusion on RCS in bistatic radar and the empirical angle on echo signal decorrelation of monostatic radar well,which verifies the proposed model.The research will provide reference for topics such as detection,tracking and system configuration in distributed MIMO radar.关键词
