Abstract :
The use of a self-affine surface to test three phase unwrapping algorithms, cut-line, least-squares and a region-growing is discussed. The methods were chosen to be a representative set of modern phase unwrapping methods. Phase unwrapping is one of the most critical processes in interferometric SAR
