Airborne Rain-Rate Measurement with a Wide-Swath Radar Altimeter

Journal of Atmospheric and Oceanic Technology, 2014
Abstract The NOAA Wide-Swath Radar Altimeter (WSRA) uses 80 narrow beams spread over ±30° in the cross-track direction to generate raster lines of sea surface topography at a 10-Hz rate from which sea surface directional wave spectra are produced.

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 ...
