Satellites observing and measuring the Earth’s surface with electromagnetic waves are subject to atmospheric path delays. These atmospheric effects on radar signal propagation modify the signal velocity and direction and can be considered by simple modeling. In order to increase the geolocation accuracy of spaceborne SAR applications we developed a software tool that accounts for atmospheric pa...

RESUME The German Remote Sensing Data Center (DFD) of the German Aerospace Center (DLR) is an element in the network of the Multimission Facilities of ESA and responsible among other tasks for SAR processing. The DLR has implemented a service for value added products over land. This service can support the user community with preceise geocoded products in addtion to the standard products of ESA...

Through the use of Envisat ASAR Alternating Polarization (AP) mode data, the Applied Science Section of the Canadian Ice Service (CIS) has been investigating the utility of multiple polarization SAR data for operational ice monitoring. This work will help CIS develop initial guidelines and recommendations for use of multiple polarization data in preparation for future SAR missions, RADARSAT-2, ...

A new microwave backscattering model for vegetated areas was developed. It enables the separation of the soil and vegetation contributions to the backscattering coefficient, which is crucial to obtain reliable simulation results for different imaging geometries. It is shown, that the vegetation influence on the signal can be directly derived from ENVISAT ASAR alternating polarization data. It i...
