The processing of hexagonally sampled signals with standard rectangular techniques: application to 2d large aperture synthesis interferometric radiometers
In Earth observation programs there is a need of passive low frequency (L-band) measurements to monitor soil moisture and ocean salinity with high spatial resolution 10-20 km, a radiometric resolution of 1 K and a revisit time of 1-3 days. Compared to total power radiometers aperture synthesis inter...
