摘　　要：对建筑物安全的诊断已经成为工程学科中一个重要领域,能进行有效的形变监测是减少建筑物安全隐患的主要手段之一。提出一种微波雷达的目标形变监测系统,采用高精度旋转云台搭载微波雷达组成雷达扫描仪作为数据源,以python函数作为数据分析平台,通过空间球坐标变换分析数据,对目标进行形变监测。该系统高抗干扰、全天候和低成本的优势,在时间和空间上都能满足对建筑物的早期形变监测的目的。其测量形变值精度能够达到毫米级,相对误差为3.2%,为工程建筑物形变监测提供了一种技术手段。The diagnosis of building safety has become an important field in the engineering discipline, and effective deformation monitoring is one of the main means to reduce the hidden dangers of building safety. This paper proposes a target deformation monitoring system for microwave radar. A high-precision rotating gimbal equipped with a microwave radar is used as a data source, a python function is used as a data analysis platform, and the target is deformed through space ball coordinate transformation analysis data. The system has the advantages of high anti-interference, all-weather and low cost, and can meet the purpose of early deformation monitoring of buildings in time and space. The accuracy of measuring deformation value can reach millimeter level, and the relative error is 3.2%, which provides a technical means for engineering building deformation monitoring.
