N2 - Herein is proposed a novel high-steep rock slope landslide monitoring system based on the configuration of multi-static multiple-input multiple-output synthetic aperture radar (MIMO-SAR). In this system, three spastically distributed radars are employed. Each is a Ku-band MIMO-SAR, transmitting mutually orthogonal waveforms and sensing the slope movement from different view angles. The three radars can then achieve the deform measurements in the three line of sight (LOS) directions. After an effective fusion of these measurements, the deform vector, with direction and amount, can be resolved. This vector is particularly important for risk warning as well as for understanding the motion mechanism of landslide. Moreover, the data acquisition period can be largely reduced, since the use of MIMO radar allows a simultaneous sampling of the scene echo. The time decorrelation is therefore very small, and hence high measurement accuracy can be expected. It can be proved that, using this system, the three-dimensional accuracy can reach 0.1 ∼ 1 mm. Simulations and experimental datasets are used to validate this proposal.
