Open publisher page 0 citations

Abstract

A novel approach is proposed in this paper to exploit the shuttle radar topography mission(SRTM) digital elevation model(DEM) in the interferometric synthetic aperture radar(InSAR) data processing.This algorithm can be applied to facilitating phase unwrapping problem.The purpose of this paper is to fill this gap by introducing the SRTM DEM as guidance for phase unwrapping.Some experimental results with JESR verify the theoretical analysis and show that the method can improve the performance of the phase unwrapping to a great extent.
