IEEE Transactions on Microwave Theory and Techniques, 1992
A brief review of the historical development and principles of satellite radar altimetry is presented, with special emphasis on the unique capability of the microwave altimeter to provide valuable information for global geoscientific studies. Altimeter data over the ocean are used to monitor mean sea levels, wave height, wind speeds, and surface ...

Broadview radar altimetry toolbox
2016The universal altimetry toolbox, BRAT (Broadview Radar Altimetry Toolbox) which can read all previous and current altimetry missions’ data, incorporates now the capability to read the upcoming Sentinel-3 L1 and L2 products. ESA endeavoured to develop and supply this capability to support the users of the future Sentinel-3 SAR Altimetry Mission. BRAT is

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.

Radar altimetry of South Tharsis, Mars
Icarus, 1980The paper discusses Martian altitudes measured by radar during the oppositions of 1971 and 1973 using the 64-m antenna at Goldstone, Calif. The resultant topographic profiles substantiate a zonal classification of the volanic flows blanketing the south flanks of Arsia Mons, and they confirm the existence of a secondary, parasitic shield, attached from ...

Multibeam radar altimetry: spaceborne feasibility
IEEE Transactions on Geoscience and Remote Sensing, 1991An analysis of the inherent height and spatial resolution of an off-nadir radar altimeter is presented. For the general case, mean-square height uncertainty is shown to be proportional to the cross-track beamwidth divided by the along-track beamwidth. Thus, the cross-track beamwidth should be minimized and the along-track beamwidth maximized, subject ...

Radar altimetry of large Martian craters
Icarus, 1989A total of 108 13-cm wavelength scans conducted for the 23 to -22 deg latitude regions of Mars during the 1971-1982 oppositions are of sufficiently high resolution to allow elevation differences of as much as 3 km over less than 10 deg longitude to be observed; most of this local relief is furnished by structural elements of impact craters.
