Abstract

Spaceborne synthetic aperture radar (SAR) multi-pass interferometry is a technique based on the exploitation of the phase differences between two complex radar images taken from two slightly separated positions on different dates (1993). This measure contains not only geometric and topographic information, but also differential information covering land or atmospheric changes between the two scenes observed (1995). These atmospheric artifacts can be an obstacle to the production of digital terrain models (DTM) from multi-pass SAR interferometry
