Design of a Monopulse SAR System for the Determination of Elevation Angles.

Kurzfassung

Terrain height variations in mountainous areas cause problems in the radiometric correction of SAR images. We propose a novel SAR system which exploits the monopulse principle to determine the elevation angle and thus the height at the different parts of the image. From the ratios of images radiometrically modulated by the difference and sum antenna pattern in cross-track direction, we can calculate the appropriate elevation angle at any point in the image.
