MIMO雷达信号处理综述

摘要

MIMO (multiple-input multiple-output) radar is a kind of new concept radar and is developing quickly.Currently,its core problem is to solve signal processing of MIMO radar.A systematically general introduction to MIMO radar is reviewed from aspects of estimation of target direction,velocity,distance,and waveform design,antenna array,etc.In addition,current research condition and the ex istent problem of coherent MIMO radar and statistical MIMO are introduced respectively,and the direction of further research is proposed.%MIMO雷达作为一种新概念的雷达系统正在快速地发展,目前其核心问题是要提高MI-MO雷达的信号处理能力.系统地从目标方位、速度、距离估计,以及波形设计、天线阵列设计等方面对MIMO雷达信号处理作了系统的综述.介绍了当前相干MIMO雷达和统计MIMO雷达各方面信号处理的研究现状和存在的问题,并提出了进一步研究的方向.
