Satellite Radar Altimetry Over Arid Regions
International Geoscience and Remote Sensing Symposium, 'Remote Sensing: Moving Toward the 21st Century'., 2005The response of the Seasat radar altimeter to a variety of arid surfaces in the Taklimakan Shamo in China is investigated. Comparisons with maps based on aerial photography and Landsat imagery demonstrate that the radar altimeter detects differences in surface morphology and provides topographic information complementary to the image data.

Advanced processing of altimetry Cassini radar data
2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM, 2011The Cassini RADAR is a Ku band multimode instrument capable of providing topography information of Titan's surface when operating in altimetry mode. During the last six years (January 2005 to 2011) Cassini has performed 71 Titan's fly-bys and several observations have been collected in Altimetry mode.

A quantitative approach to the scientific production on radar altimetry
Advances in Space Research, 2021Abstract Radar altimetry is a high-precision, remote-sensing technique relevant for different areas of Earth observation like sea, land, and ice surface topography; sea level and floor; or wave heights. This paper provides an analysis of the scientific and technical literature on Radar Altimetry.

Radar Altimetry: Introduction and Application to Air-Sea Interaction
2008Radar 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

A radar equation for snow-covered targets in radar altimetry
Waveform simulators are commonly used to retrack ice surface elevations from radar altimeter observations. Most simulators apply the radar equation to estimate backscattered power, but this formulation often overlooks refraction at the snow surface. Because snow alters the propagation direction of the radar pulse, refraction modifies both the incidenceHoyeon Shi, Rasmus Tonboe

Interferometric Swath Radar Altimetry for the study of the Cryosphere
2022Reference and repeat-observations of land-ice topography is critical to identify causal links between climate and ice trends, generate an accurate record of ice mass balance, and quantify land ice contribution to sea level change. Over the last 30 years, radar altimetry has been instrumental in monitoring ice sheets and their contribution to sea level ...

Radar Altimetry: Past, Present and Future
2010This 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 response from rough surfaces
Photogrammetria, 1987Abstract 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 ...
