A novel ground based multi bistatic radar for interferometric measurement of displacement vector

A novel ground based multi bistatic interferometric radar sensor has been realized in order to measure the three dimensional displacement vector of civil structures as buildings, bridges and towers. Data processing techniques were developed to determine the position of each target and to calculate three dimensional displacement starting from mono dimensional displacement measured from three different positions in space. Experimental tests were finally carried out in controlled environment in order to validate the proposed technique and to assess the accuracy of displacement´s measurement.
