The RADAR DEM Extraction process and algorithms allows us to create Digital Elevation Models (DEMs) from stereo RADAR data. Image correlation is used to extract matching pixels in two overlapping images and then use the sensor geometry from a computed math model to calculate x, y, and z positions. RADAR DEM extraction allows us to perform batch epipolar generation, batch the DEM extraction process, geocode DEMs, and create absolute or relative DEMs.
