Abstract

Phase altimetry has been recently introduced for high precision measurements in satellite bistatic global navigation satel-lite system refiectometry in the presence of coherent scattering. This work introduces differential altimetry concept via a simulation study. The phase difference between two contigu-ous specular points paths is exploited to reduce atmospheric effects and systematic errors occurring over closely spaced paths. The work also introduces an oversampling technique to mitigate unwrapping errors.
