An Interferometric W-BAND Radar for Large Structures Monitoring

Interferometric radars are widely used for static and dynamic monitoring of large structures as bridges, culverts, wind turbine towers, chimneys, masonry towers, stays cables, buildings, and monuments. The most of these radars operates in Ku-band (17 GHz). Nevertheless, a higher operative frequency could allow to design smaller and lighter equipment. The aim of this paper is to verify if a commercial 77 GHz radar designed for automotive applications could be used as interferometric radar for static and dynamic monitoring of large structures. The obtained preliminary results in controlled conditions are very promising.
