A NEW SET OF TOOLS FOR ALL ALTIMETRY USERS The field of satellite radar altimetry has matured to a point where it is now time to encourage a multimission approach and conceive an "all-altimeter" toolbox including a tutorial. Such an integrated approach and view is vital not only for assessing the current status of what offers altimeter products but ...

Proceedings of SOUTHEASTCON '96, 2002
A next generation compact, Ku-band, pulse compression radar altimeter (RA) measures sea surface topography to a few centimeters accuracy and provides scientific data for assessing ocean circulation, mean sea-level change and other ocean features. The integrated RA is comprised of a basic altimeter, a water vapor radiometer (WVR) for correcting RA range

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 ...

The characteristics of nadir versus off-nadir altimetry are reviewed and contrasted and a potentially serious problem has been pointed out that has been overlooked by earlier investigators, who focused on the nongeophysical error sources in off-nadir altimetry.

Indus river water level monitoring using satellite radar altimetry
Advances in Space Research, 2020Satellite altimetry-based monitoring of water bodies is an advanced and cost-effective approach, mainly for regions where gauge density is low, as is the case of the Indus River in Pakistan.

Airborne Lidar Altimetry in support of Radar Altimetry
2016In a series of experiments between 2011 and 2016, in the Gulf of Mexico and off the coast of California, directional wave field and the sea surface height anomaly (SSHA) measurements were collected by the Scripps Modular Aerial Sensing System (MASS) waveform scanning lidar.

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 ...
