摘    要:
多输入多输出(multiple-input multiple-output, MIMO)技术用于多通道雷达,可以扩展阵列孔径,提高系统分辨力。证明了一个发射阵元和一个接收阵元通过分时移位模拟MIMO雷达工作状态的可行性,提出以一发一收构建一套MIMO雷达试验系统。给出了系统搭建原理和测量方法,设计了实孔径阵列和等效阵列外场试验,结果表明,阵列孔径得到了扩展,成像与DOA估计的分辨力得到了提高。

关 键 词:多输入多输出雷达  波达方向  成像  外场试验

Abstract:
MIMO technology having been applied,the multichannel radar can extend the array aperture and improve the performance of resolution.This paper shows that an MIMO radar may be simulated through the time-sharing motions of a single transmitter and a single receiver,and an MIMO radar simulated experimental system is constructed by a single transmitter and a single receiver.The constructed principle and measures are given.Finally,the experiment using real array and equivalent array shows the array virtual apertu...
Keywords:multiple-input multiple-output (MIMO) radar  direction-of-arrival (DOA)  imaging  field experiment
