Parameter estimation for peaky altimetric waveforms [PDF]

open access: yes, 2013
Much attention has been recently devoted to the analysis of coastal altimetric waveforms. When approaching the coast, altimetric waveforms are sometimes corrupted by peaks caused by high reflective areas inside the illuminated land surfaces or by the ...
