DInSAR (Differential Interferometric Synthetic Aperture Radar) is already well-known as an effective application technique of SAR data for the displacement measuring of the ground surface. The authors are developing a drone-borne SAR that can apply DInSAR analysis. In Japan, which has suffered various disasters, the slope stability monitoring for active volcanoes, landslide slopes, open-pit mines, etc., and the maintenance management for aging infrastructures are considered important issues. Therefore, by effectively utilizing the position information and terrain information obtained from the satellite data, we have started an R&D project aiming at practical application of DInSAR technology with drone-borne SAR.
