中文摘要	由于阵元数目有限,传统的速度合成孔径雷达(VSAR)存在方位定位模糊的问题,难以准确地定位地面高速运动目标.本文将多输入多输出(MIMO)雷达与VSAR相结合,提出了新体制MIMO-VSAR雷达及其一种实用的优化阵列配置.与传统VSAR相比,MIMO-VSAR利用同时发送的正交信号,获得了远多于阵元数目的等效密集空间采样,有效地提高了动目标的无模糊定位范围.理论分析和仿真结果均证明了MIMO-VSAR及其优化配置的有效性.; Due to the limitation of array element number,the conventional velocity synthetic aperture radar(VSAR),may suffer from the azimuth location ambiguity and mislocate fast moving targets.To solve this problem,a novel VSAR named MIMO-VSAR and an optimized array configuration of MIMO-VSAR are proposed based on the multiple-input multiple-output(MIMO) radar in this paper.Compared with the conventional VSAR,the MIMO-VSAR may greatly increase the spatial sampling rate and extend unambiguous velocity estimation range by transmitting and receiving multiple waveforms simultaneously.Furthermore,the analysis and numerical experiments are provided to demonstrate the effectiveness of the MIMO-VSAR and its optimal configuration.
