Abstract

We propose a new method to determine the level of remote water bodies with centimeter accuracy. The method is based on accurately determining the distance between the SAR antenna and the virtual phase center of a device that produces a double or triple bounce reflection with a well-known phase center. In the paper we describe a special mechanical arrangement to produce such a reflection and we report about results of first experiments.
