Abstract
Ground-based synthetic aperture radar (GB-SAR) has become an efficient and accurate micro-variation monitoring technology, which has played an important role in the micro- deformation monitoring of open mines, dams, geological disasters and some other fields. However, GB-SAR is limited by linear orbits and cannot be used for Omnidirectional micro deformation monitoring. [1] A portable omnidirectional micro deformation monitoring radar system has been successfully developed which is capable observing large scenes featuring with large angle of view. In addition, total weight of the radar system less than 20 kg and it can be operated by single person in areas where large equipment cannot be deployed. The portable omni-directional micro deformation monitoring radar improve the inadequacies of ground-based linear orbit synthetic aperture radar.
