An analysis of radar observations in C band combined with models is proposed to study some of the ocean surface properties and their relation with the sea surface backscatter. The electromagnetic part of the models is of different kinds: composite Bragg model with or without including effect of wave breaking zones on the normalized radar cross-section(More)
Oceanography greatly benefits from remote sensing satellites for global monitoring and forecast of the sea surface. The CFOSAT (China France Oceanography SATellite) mission, whose launch is planned for 2013, should embark two radar payloads to monitor wind and waves over the ocean. One of this two radar instruments is called SWIM (Surface Waves(More)
The "Cooperative Airborne Radiometer for Ocean and Land Studies" (CAROLS) L-Band radiometer was designed and built as a copy of the EMIRAD II radiometer constructed by the Technical University of Denmark team. It is a fully polarimetric and direct sampling correlation radiometer. It is installed on board a dedicated French ATR42 research aircraft, in(More)
A renewal of interest for the radiometric L-band Sea Surface Salinity (SSS) remote sensing appeared in the 1990s and led to the Soil Moisture and Ocean Salinity (SMOS) satellite launched in November 2009 and to the Aquarius mission (launched in June 2011). However, due to low signal to noise ratio, retrieving SSS from L-band radiometry is very challenging.(More)
Observational results derived from the airborne C-band scatterometer RESSAC looking at small incidence angles (521 ") were acquired in the vicinity of the Gulf Stream during the Surface Wave Dynamics Experiment in February and March 1991. Although the instrument was primarily designed to study the directional spectra of long waves, it is also possible to(More)
The CAROLS, L band radiometer, is built and designed as a copy of EMIRAD II ra-diometer of DTU team. It will be used in conjunction with other airborne instruments (in particular the C-Band scatterometer (STORM) and IEEC GPS system) in coordination with in situ field campaigns. Common objectives for land and sea surface investigation are i) to provide(More)
