Sea State Bias in Radar Altimetry Revisited

Marine Geodesy, 2010
Sea state bias (SSB) is calculated anew for each radar altimeter. The input data are sea surface height (h) differences, separated in time by at most one repeat cycle, or the difference between measured h and a time-mean sea surface, an approach called here “differences from the mean” (DFM).

Radar altimetry response from rough surfaces

Photogrammetria, 1987
Abstract Radar altimetry from SKYLAB, GEOS-3 and SEASAT has clearly shown the capability of the technique for measurements of wave-height, tidal action and the deviation from the perfect geoid. In order to further evaluate the performance over ice and land areas, a simulation model was developed, which estimates the pulse response from an arbitrary ...

Radar altimetry of Mercury: A Preliminary analysis

Journal of Geophysical Research: Solid Earth, 1986
Measurements of Mercurian topography based on Arecibo radar observations are presented. The data, which were obtained from 1978 to 1984, cover much of the equatorial zone of Mercury between 12°N and 5°S latitude. Over thirty continuous altitude profiles were obtained, each spanning from 20 to 90 degrees of longitude at a resolution of 0.15° (longitude)

Radar Altimetry: Past, Present and Future

2010
This chapter describes the radar altimetry principle and relates the radar altimetry missions since the first demonstration mission, Skylab in 1975, to the most recently planned mission, Sentinel-3, extending to a proposed revolutionary two-dimensional topography mission, SWOT.

Radar Altimetry: Introduction and Application to Air-Sea Interaction

2008
Radar altimeters are among the more common satellite-borne Earth Observation instruments with a long history including continuous data since 1991. They are also exceptionally versatile providing informa- tion on sea level, ocean dynamics, wind speed and a number of wave pa- rameters. Radar altimetry is a "point" rather than a "swath" instrument so that

Geoid undulations mapped by spaceborne radar altimetry

1986
Abstract Were the ocean and atmosphere at rest, the sea surface would describe a surface of constant gravitational potential. This equipotential surface is called the geoid. Removal of a simple reference surface (spheroid or ellipsoid) leaves geoid anomalies, or undulations of various wavelengths.

ALTIMETRY BY CASSINI RADAR: PROCESSING AND SIMULATION

2009
The Cassini mission, that is a joint NASA/ESA/ASI effort, has recently offered the unique possibility of exploring Titan, the largest moon of Saturn, that is the only satellite in the solar system to host an appreciable atmosphere, which unfortunately made the surface below very difficult to be observed from the Earth with optical instruments. In fact,
