MIMO技术不仅可以提高通信系统的性能，而且可以提高雷达系统的性能。在本文中，我们提出了一个准MIMO多普勒雷达室内人体检测。在室内测量中，墙壁、地板和家具的多径反射常常使人体检测困难。多普勒滤波器的引入，以消除这些不希望的响应和提取雷达回波的人在运动之前的目标检测。同时将基于Khatri-Rao矩阵积的虚拟阵列技术引入MIMO雷达检测中。实验结果显示性能的改善，特别是在角分辨率。
MIMO technique can improve system performance not only communication system but also radar system. In this paper, we propose a quasi-MIMO Doppler radar for indoor human detection. In the indoor measurements, multipath reflections by wall, floor, and furniture, often make human detection difficult. Doppler filtering is introduced to remove these undesired response and extract radar echoes by human in motion before target detection. Also virtual array technique based on the Khatri-Rao matrix product is introduced in the MIMO radar detection. Experimental results are reported to shown performance improvement especially in angular resolution.
