Abstract

The target of high resolution digital terrain elevation sequence is to obtain 3-D representation of a terrain's surface. In this work we used interferometric technique which is based on the analysis of the phase difference between the signals received at two antenna position. Under suitable conditions, the resulting DEM of this method is locally the most precise one. This work is concerned with the exploitation of radar SLC images of the Las Vega area acquired on 24 May and 25 May 1994, the first is taken as the master image and the other as slave. We have developed an interferometric process beginning with the implementation of a co-registration algorithm for the images. Then we developed the flatearth phase elimination from the interferogram. We also developed a filter in order to minimiz the existing noise. At the end remove the effect of under sampling to get a good result in the final step of the process which is the unwrapping step.
