Soil Moisture Retrieval Using Gnss-R Data [PDF]
2020 Mediterranean and Middle-East Geoscience and Remote Sensing Symposium (M2GARSS), 2020 The aim of this study is to propose an inversion algorithm for CYGNSS constellation data, which can be used for the monitoring of soil moisture. A change detection approach based on a 21-month CYGNSS data time series is proposed, and is processed to retrieve daily average reflectivity over a grid with a spatial resolution equal to $0.5 ^{\circ} \mathrm{

Sea state monitoring using coastal GNSS‐R [PDF]
Geophysical Research Letters, 2004 We report on a coastal experiment to study GPS L1 reflections. The campaign was carried out at the Barcelona Port breaker and dedicated to the development of sea‐state retrieval algorithms. An experimental system built for this purpose collected and processed GPS data to automatically generate a times series of the interferometric complex field (ICF ...
