Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]

, 2010
Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform
