Hybrid Geometric Calibration Method for Multi-platform Spaceborne SAR Image with Sparse GCPs

Hybrid Geometric Calibration Method for Multi-platform Spaceborne SAR Image with Sparse GCPs

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).However, it is very difficult to obtain GCPs that covering large-scale areas, especially in the mounta...
