Abstract

We propose a novel design of a SAR system which exploits the monopulse principle to determine the elevation angle and thus the height at the different parts of a SAR 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. In this paper, we present design considerations for a corresponding airborne SAR system in X-Band and give estimates of the error due to system noise and azimuth ambiguities as well as the expected performance and precision in topographic mapping.
