摘要： 毫米波雷达可获取高频率、高精度形变位移数据，但雷达仅能获取目标径向形变分量，亟须对雷达分布式组网监测获取目标三维形变问题进行研究。首先对自研的地基毫米波雷达系统进行简要介绍，进而在论述系统射频信号模型的基础上提出一种建筑结构特显点目标三维形变位移及频谱监测方法，最后开展桁架厂房建筑火灾倒塌监测预警试验，通过3台雷达同步监测获取建筑结构关键目标三维形变结果。研究表明：毫米波雷达分布式组网监测可在真实火场下有效获取建筑特显点目标三维形变分量，为建筑火灾倒塌监测预警模型提供有效输入数据，未来可在应急救援、建筑工程健康监测等方面推广应用。

Abstract: Millimeter-wave radar can obtain high-frequency, high-precision deformation displacement data, but because the radar can only obtain the target radial deformation component, it is urgent for radar distributed network monitoring to obtain the target three-dimensional deformation. In this paper, the self-developed ground-based millimeter-wave radar system is firstly briefly introduced, and then a three-dimensional deformation displacement and spectral monitoring method of the target at the special point of the building structure is proposed on the basis of the RF signal model of the system, and then the fire collapse monitoring and early warning test is carried out for truss factory buildings, and the three-dimensional deformation results of the key targets of the building structure are obtained through the synchronous monitoring of the 3 radars. The study shows that the distributed network monitoring of millimeter wave radar can effectively obtain the three-dimensional deformation components of the target at the special point of the building under the real fire scene, and provide effective data input for the monitoring and warning model of building fire collapse, which can be popularized and applied in the future in the aspects of emergency rescue and health monitoring of building engineering.
