Elevation Model Generation by Using Radarsat Images

Like all other Synthetic Aperture Radars (SAR), Radarsat is very sensitive to the terrain shape. Fine details of the ground clearly appear in its image products which enable us to map regions generally not visible by optical systems. Moreover, in the case of tropical and equatorial regions, precise maps are often not available, since the elevation data is totally unknown. The objective of our project is to implement a strategy for computing elevation model from the SAR data acquired by this system. More precisely, we describe in this paper the radarclinometric method that we have performed.
