| Abstract: | 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. |
