Radar Altimetry for Land Applications
1989An international programme for polar earth observations will be established by NASA /ESA/NASDA, starting in 1995. Among many other instruments, the first NASA mission (EOS-1) will possibly incorporate a sensor system for measuring global land topography.

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.

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.

Spatial analysis of the electromagnetic bias in radar altimetry
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003Measurements of the electromagnetic bias have shown that bias increases with wind speed until about 11 m/s and then begins to decrease. Two possible causes are investigated. First, it could be due to a shift in the backscatter power modulation to the forward or rear face of the wave crests. Second, it could be due to the backscatter power becoming more

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

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.
