Abstract: The use of multiple InSAR images of the same area for phase unwrapping is discussed. It is shown that by combining the information in the two InSAR images, the ambiguity interval of the phase angle can be considerably lengthened, which will facilitate unwrapping. Three methods for combining multiple InSAR images are proposed and their error characteristics discussed.
