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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
