Processing of Raw GNSS Reflectometry Data From TDS-1 in a Backscattering Configuration

GNSS-R Ice Sheet Altimetry in Greenland Using TDS-1 Data

Radar altimetry provides valuable measurements to characterize the state and the evolution of the Antartica and Greenland ice sheet cover. Global Navigation Satellite System Reflectometry (GNSS-R) has the potential capacity of complementing the dedicated radar altimeters incrementing the temporal and spatial resolution of the surface height measurements. In this work we perform an study of the ...

Sea surface topography retrieved from GNSS reflectometry phase data of the GEOHALO flight mission

Sea surface topography observations are deduced from an airborne reflectometry experiment. A GNSS (Global Navigation Satellite System) receiver dedicated for reflectometry was set up aboard the German HALO (High Altitude Long Range) research aircraft. Flights were conducted over the Mediterranean Sea about 3500m above sea level. A signal path model divided into largeand small-scale contribution...

Spaceborne Receiver Design for Scatterometric GNSS Reflectometry

Enhanced backscattering in a converging-beam configuration.

Enhanced backscattering (EBS) is investigated for a converging-beam geometry. We find that the functional form of the enhanced backscattering cone is preserved under a change of variables that involves the focal length of the lens and the lens-to-sample distance. In absolute terms, the effect of the lens is that the EBS enhancement cone is lowered in magnitude and narrowed in angle. The experim...

Feasibility of GNSS-R Ice Sheet Altimetry in Greenland Using TDS-1

Radar altimetry provides valuable measurements to characterize the state and the evolution of the ice sheet cover of Antartica and Greenland. Global Navigation Satellite System Reflectometry (GNSS-R) has the potential to complement the dedicated radar altimeters, increasing the temporal and spatial resolution of the measurements. Here we perform a study of the Greenland ice sheet using data obt...
