An Analysis of The NASA CSDA Bistatic Radar GNSS-R Dataset

The remote sensing of the Earth’s surface through a variety of spaceborne platforms has a long history of investigation. The selection of one sensing technology over another is typically governed by the geophysical products of interest and requirements of spatial and temporal sampling. Recent studies have highlighted the utility of GNSS-R (Global Navigation Satellite System-Reflectometry) measurements for the sensing of multiple geophysical properties. The modest cost of GNSS-R receive-only platforms also promotes the simultaneous launch of multiple receivers, further improving revisit times, and the L-band frequency used provides all weather operations given the insensitivity of L-band measurements to cloud cover and even heavy rain rates.
