摘　　要：毫米波雷达在工业界有着广泛的应用,尤其在室内态势感知和人员目标跟踪上有着精确度高、鲁棒性强、全时段可用的特点。毫米波雷达室内应用的基础是房间大小的自动测量。本文针对毫米波雷达室内大小测量的问题,对接收到的雷达数据立方进行数据重整、距离维脉冲压缩、capon波束形成谱估计得到静态热度图,然后对热度图数据做恒虚警率检测得到点云数据,最后在点云数据的基础上进行最小二乘得到房间尺寸。Mmwave radar has wide application in industry.It shows characters of high precision,strong robustness and all-time usability when used in room situation awareness and people target tracking.Automatic measurement of room size is basement of indoor application of mmwave radar.This article deals with the problem of measuring room size.First,data arrangement,pulse compression and capon-BF is used on data cube to get static heatmap.Then,constant false alarm rate is utilized on heatmap to get pointcloud.At last,least square is used on pointcloud to attain room size.
