Abstract
SMOS Side Lobe Level (SLL), which is caused by the limited coverage of the measured visibility samples in the frequency domain, is responsible for non-negligible radiometric errors at pixels placed close to large brightness temperature transitions (e.g. coastline, ice-sea border, RFI, sun reflection, etc.). In order to mitigate this effect the visibility samples are tapered by means of a Blackman window before the image inversion procedure is undertaken. However, the theoretical SLL performance ...
