中文摘要：

MIMO雷达是近几年发展起来的一种新体制雷达，由于同时采用了空间分集与信号分集技术，它表现出了许多不同于传统雷达的特性。该文着重研究了MIMO雷达与传统相控阵雷达多脉冲条件下的检测性能，建立了两种体制雷达多脉冲条件下的目标检测模型，理论给出了两种体制雷达对时间上服从快、慢起伏目标的检测门限和检测概率表达式，同时通过对两种目标模型下MIMO雷达和相控阵雷达的多脉冲理论检测性能的对比分析。

英文摘要：

Multiple-input multiple-output（MIMO） radar is a new type of radar system developed in recent years. Because of application of space diversity and signal diversity techniques, the target detection performance of MIMO radar have differences from conventional phased array radars. This paper researches detection performances of MIMO radar and phased array radar based on multiple pulses. Firstly, the target detection models of MIMO radar and phased array radar based on multiple pulses are respectively presented. Then the detection threshold and detection probability of fast fluctuation and slow fluctuation targets are presented theoretically. Finally, their detection performances are compared by simulations. Some beneficial conclusions are given.
