摘　　要：为满足建筑结构全天候、高精度及低成本的位移监测要求,提出了基于相位测量的微波位移测量方法。该方法以微波作为全天候测量信号,利用高精度相位测量实现高精度位移监测,并采用低成本的标准频率器件搭建位移测量系统。实验结果表明:系统位移测量精度可达0.12 mm,并验证了系统具有全天候、高精度、低成本的位移监测特性。In order to meet requirements of displacement monitoring for architectural structures such as working under all-weather conditions, high precision and low-cost, a method for displacement detection with microwave based On phase t is proposed. In the method, microwave signal is used as measurement signal for all- weather work, and the high precision phase measurement is used to achieve high precision displacement monitoring, and devices of low-cost standard frequency are adopted to build up system of displacement measurement. Experimental results show that displacement measurement precision of system reaches to O. 12 mm, and verify that the system has the features of all-weather work, high precision and low cost.
