Multi-Monostatic Interferometric Radar for Bridge Monitoring

In recent years, interferometric radar has been extensively used as a sensor for static and dynamic monitoring of bridges. Generally speaking, can only detect displacement components along the view direction. As movement real bridge or large structure be rather complex, this limitation significant drawback in engineering practice. order to overcome limitation, article, multi-monostatic retrieving vector is proposed. It basically multiple input, output (MIMO) radar, equipped with transponder that consists pair antennae, relative amplifiers, connected radiofrequency (RF) cable. This arrangement allows simultaneous detection two independent components. The was successfully tested both controlled environment field on crossing Arno river Florence, Italy.
