Spaceborne receiver design for scatterometric GNSS reflectometry

, 2012
Global Navigation Satellite System-Reflectometry (GNSS-R) is an innovative technique for remote sensing. It uses reflected signals from the navigation constellations to determine properties of the Earth’s surface. The primary focus of this work is the remote sensing of the ocean by measurement of surface roughness.

GNSS Reflectometry and Passive Radar at DLR [PDF]

, 2008
The presentation mainly summarises a planned GNSS reflectometry satellite mission that has been proposed by the Microwaves and Radar Institute to the DLR programme board in close cooperation with the GFZ Potsdam. The proposal was driven by the possible opportunity to use the DLR TET-1/-2 (Technologie Erprobungs Träger, very similar to the BIRD ...
