摘要
本文介绍自主研发的轻便型变形监测雷达的原理结构和特点,并通过一系列实验对该雷达进行基本物理参数和精度的初步测试以及建筑物变形监测方面的应用实验。通过实验证明,该雷达的测量精度达到0.1mm,最远可以观测到800m外的目标,可以用于建筑物变形监测,该雷达也用于边坡、大坝、桥梁等目标的远程变形监测。同时,该雷达在重量、体积、功耗等方面有着优势,解决同类产品笨重、难以携带作业的问题。
This paper briefly introduces the principle, structure and characteristics of a portable deformation monitoring radar developed by it.Then through a series of experiments, the basic physical parameters and accuracy of the radar are preliminarily tested and the application experiments of the building deformation monitoring are carried out.Through these experiments, it proves that the precision of the radar has reached 0.1 mm, so that the target furtherthan 800 meters can be observed .The radar can be used for the monitoring of the deformation of the building, and for remote deformation monitoring of the targets such as slope, dam and bridge.At the same time, the radar has a great advantage in weight, size, and power consumption, has no problem of being heavy and difficult to carry the same kind of products, expanding the scope of application.
