Abstract

For implementing the radiometric correction of spaceborne SAR image produced by the imaging processor using equivalent-squint wavenumber domain algorithms, this paper derivates the gain introduced in the processing of this algorithms and give out the equation for calculating SAR imaging processor gain based on equivalent-squint wavenumber domain algorithms. Simulation result demonstrates the equation is right and the calculation precision is relatively high.
