多输入多输出（MIMO）技术应用于多级雷达提供了许多优点，包括提高分辨率和灵敏度。根据雷达的工作模式、阵列设计和环境，这些优点可能很重要，也可能不重要。本文提出了一种简单的地面动目标指示（GMTI）雷达检测分析模型，并将其预测结果与仿真结果进行了比较。从最小可探测速度、区域搜索速率和阵列旁瓣等方面对传统的单输入多输出（SIMO）和MIMO GMTI雷达进行了比较。针对MIMO雷达，给出了不同性能指标下的最优波形互相关矩阵。最后，边界的MIMO阵列均匀采样的虚拟孔径。
The application of multiple-input multiple-output (MIMO) techniques to multistage radar offers a number of advantages, including improved resolution and sensitivity. Depending upon the radar's mode of operation, the array design and the environment, these advantages may or may not be significant. In this paper, a simple analytic model for ground moving target indicator (GMTI) radar detection is presented and its predictions are compared with simulation. Conventional single-input multiple output (SIMO) and MIMO GMTI radars are compared in terms of minimum detectable velocity, area-search rates and array sidelobes. Optimal waveform cross-correlation matrices are identified for MIMO radars, given different performance criteria. Finally, bounds are developed for MIMO arrays with uniformly sampled virtual apertures.
