Important progresses have been obtained during the last years in the science of processing high resolution radar images. They derive from several facts. At rst we have a better knowledge of the signal statistical properties allowing improved performances for the detection and ltering stages. Then, these low level stages have received a great attention and(More)
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(More)
Synthetic aperture radar (SAR) imagery is now well-known as it is actively used in various remote sensing domains such as oceanography, geology, environment surveillance, cartography, etc. In this paper, we describe a new method for computing an elevation map from a single SAR image. Our method begins by reconstructing an approximate elevation map of the(More)
