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 measurement is proposed. In the method

microwave signal is used as measurement signal for allweather 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 0. 12 mm

and verify that the system has the features of all-weather work

high precision and low cost.
