摘　　要：多发多收(MIMO)雷达技术在针对点目标的探测研究中已经取得丰硕成果,其技术优势十分明显。如何将此技术应用到气象雷达观测弥散体目标中,则需要进行分析。文中从现有的研究成果出发,提出一种分布式MIMO气象雷达系统的结构形式,分析分布式MIMO气象雷达系统的基本概念,推导了分布式MIMO气象雷达方程,给出了该系统下多普勒速度和双偏振参数的定义。基于上述理论进行了仿真分析,结果表明:分布式MIMO气象雷达技术切实可行,在气象探测中能发挥出一定的优势。MIMO radar technology has made great achievements in the detection of point targets,and its technical advantages are obvious.It needs to be analyzed that apply this technology to meteorological radar observation of dispersion targets.Based on the existing research results,a structure of distributed MIMO weather radar system is proposed in this paper.The basic concept of distributed MIMO weather radar system is analyzed and its equations are derived.The definitions of Doppler velocity and dual polarization parameters of the system are given.After this theory,a simulation is done and the results show that the distributed MIMO weather radar technology is feasible and can play a certain advantage in meteorological detection.
