Abstract

Synthetic Aperture Radar images reveal geometric and radiometric distortions that are caused by terrain undulations. It is necessary to eliminate the distortions before the measurement of geophysical and biophysical parameters from the SAR images. The traditional method based on a single SAR image can not totally eliminate the geometric and radiometric distortions that are caused by variable terrain. In this paper a new intact operation system based on two-looking direction RADARSAT-2 images is put forward which can eliminate the geometric and radiometric distortions. This new operation system consists of 4 major steps and is applied to the test area under investigation.
