Abstract :
One of the most critical of environmental parameters yet to be adequately measured is sea surface salinity, which impacts major ocean circulation and a number of biological oceanic processes. We discuss here the design of a new digital radiometer system to address the issues surrounding the accurate mapping of sea surface brightness temperatures at L-band with high spatial and temporal resolution, and suitable for deployment on small long endurance UAVs. The lobe-differencing correlation radiometer employs a highly stable design and digital processing using demonstrated techniques for anthropogenic radio frequency interference mitigation.
