HYBRID GEOMETRIC CALIBRATION METHOD FOR MULTI-PLATFORM SPACEBORNE SAR IMAGE WITH SPARSE GCPS
SAR image geometric calibration R-D model multi-platform TerraSAR-X TanDEM-X Gaofen-3
2018/5/15
Geometric calibration is able to provide high-accuracy geometric coordinates of spaceborne SAR image through accurate geometric parameters in the Range-Doppler model by ground control points (GCPs). H...

SPOT 5 satellite was launched on May, 4th, 2002. It has some new distinguished characteristics, for example that its ephemeris and attitudes on orbit can be accurately measured, recorded and distribut...
SAR IMAGE GEOCODING USING A STEREO-SAR DEM AND AUTOMATICALLY GENERATED GCPs
Automation Control strategies DEM Geo-referencing RADARSAT Simulation Spatial data Stereo SAR
2014/12/29
SAR image geocoding needs an accurate DEM, but such a DEM can be difficult to obtain. This paper shows that the needs of geocoding can be satisfied using the DEM generated by employing a rigorous geom...
