雷达波形分集技术在过去的几年里得到了相当大的关注。已经提出了新的雷达波形来提高检测性能和度量精度（即，角度估计性能）。本文探讨了潜在的使用波形分集技术称为多输入多输出（MIMO）雷达，以提高检测性能的缓慢移动的表面目标从一个移动的雷达平台。MIMO雷达系统通过从每个天线子孔径发射唯一的不相关波形来实现上级性能，这与在整个孔径上发射单个相干波形的传统方法相反。结果表明，利用MIMO系统有效增大雷达天线口径的能力，可以降低雷达系统的最小可探测速度。
Waveform diversity techniques for radar have gained considerable interest over the past several years. Novel radar waveforms have been proposed to improve detection performance and metric accuracy (i.e., angle estimation performance). This paper explores the potential for using a waveform diversity technique known as multiple input, multiple output (MIMO) radar to improve the detection performance of slow moving surface targets from a moving radar platform. The MIMO radar system achieves superior performance by transmitting unique uncorrelated waveforms from each antenna subaperture as opposed to the traditional approach of transmitting a single coherent waveform across the entire aperture. The results show that the radar system minimum detectable velocity (MDV) can be reduced by exploiting the ability of a MIMO system to effectively increase the radar antenna aperture.
