This work is devoted to describe the new processing techniques that are being conceived, developed and implemented at the Barcelona Expert Centre (BEC) for the generation of sea surface salinity (SSS) maps from the Soil Mooisture and Ocean Salinity (SMOS) mission. Several algorithms to mitigate the ripples and sidelobes present in the SMOS brightness temperature (TB) images, to characterize the spatial...
This work is focused on the quality improvement of ESA's SMOS (Soil Moisture and Ocean Salinity) salinity retrievals, paying special attention to coastal regions. Two correction techniques have been applied to enhance the quality of brightness temperatures: the nodal sampling for the reduction of Gibbs-like contamination and the correction of residual amplitude calibration errors for the mitigation...
Compton Cameras have been proposed as an alternative to SPECT imaging with Gamma Camera, mainly due to factors such as the electronic collimation, which allows a bigger field of view and provides further information from the acquired events if compared to devices with mechanical collimation. By contrast, this involves a higher amount of data to be processed. In medical devices this leads to waiting...
RFI (Radio Frequency Interference) sources, Sun signal and even land-sea transitions may generate large sidelobes that corrupt SMOS brightness temperature products and therefore, the quality of the soil moisture and sea surface salinity retrievals. This work focuses on the reduction of this Gibbs-like contamination in brightness temperature scenes using an alternative image reconstruction approach...
Radio Frequency Interference (RFI) is probably one of the most important limiting factors in the accuracy of the brightness temperatures measured by microwave radiometers. Due to the proximity of the “protected” L-band (1400–1427 MHz) to numerous services (communication, localization, broadcast…), this band is seriously affected by RFI, preventing ESA's SMOS mission or NASA/CONAE Aquarius mission...
This work proposes a strategy for browsing interactively sequences of high resolution JPEG 2000 remote images. These sequences can be displayed in any order (forward and backward) and following any play/timing pattern. In order to increase the quality of the reconstructions where the retrieved images are only known at the moment of the visualization, this work has proposed and evaluated a novel technique...
