Sparse Approximation of the Precision Matrices for the Wide-Swath Altimeters

Remote Sensing, 2022
The upcoming technology of wide-swath altimetry from space will deliver a large volume of data on the ocean surface at unprecedentedly high spatial resolution. These data are contaminated by errors caused by the uncertainties in the geometry and orientation of the on-board interferometer and environmental conditions, such as sea surface roughness and ...
