A New Method for DEM Generation using a Single POLSAR Flight Pass

Abstract

In this paper, we proposed a new method for DEM generation from a single POLSAR flight pass. As usual, orientation angles induced by azimuth slope can be estimated from POLSAR data. However, for DEM generation, Another condition is need to attain the orthogonal terrain slopes. Thus, shape from shading techniques, which is mostly used by the robot vision community and generate slopes in the range direction, could then be combined with polarimetry. After terrain slopes have been computed, these slopes data are then used to solve a Possion equation to estimate the elevation surface.
