Mapping Forested Floodplain Topography Using InSAR and Radar Altimetry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019An accurate floodplain digital elevation model (DEM) is an essential input for the hydraulic modeling of water flows across the floodplain. A method combining interferometric synthetic aperture radar (InSAR) and radar altimetry is presented to derive the

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.

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.

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.

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

Water surface elevation in coastal and inland waters using satellite radar altimetry
Extreme Hydroclimatic Events and Multivariate Hazards in a Changing Environment, 2019This chapter provides an overview of the satellite altimetry measurement system, how it works and how the water surface elevation is derived. Satellite altimetry had originally been designed for open ocean studies, however a decade of progress has ...

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.

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 ...
