Spaceborne SAR Image Geometric Rectification Method without Ground Control Points Using Orbit Parameters Modulation

Spaceborne SAR Image Geometric Rectification Method without Ground Control Points Using Orbit Parameters Modulation

When using the Range-Doppler model for SAR image geometric correction, the error of satellite orbit, imaging parameter and DEM elevation will affect the geometric correction accuracy. A new geometric rectification method has been presented for spaceborne SAR image. First, polynomial was used for par...
