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

Reviews of Geophysics, 1983
During the past four years satellite altimetry activities have been primarily concerned with analyses of the GEOS‐3 and Seasat data sets, and the justification and design of next generation altimetric missions and associated instrumentation.Since the last IUGG Quadrennial review of satellite altimetry [Stanley, 1979a], considerable documentation of ...

Altimetry-Gravimetry Problem: An Example
1990The topographic surface of the sea can be determined by subtracting the geoid from the geometric height of the stationary sea surface. This latter can be obtained from altimetry measurements; the former can be derived from marine gravity measurements, treated in the form of gravity disturbances.

Since the last national report to the sixteenth General Assembly, research activities in the development of appropriate techniques and the direct application of altimeter data have moved rapidly from the launch of the SKYLAB S‐193 Experiment in 1973 through the GEOS‐3 launched in June 1975 to the SEASAT‐1 launched in June 1978.

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 ...

SPIE Proceedings, 1997
Space-based laser altimeters are effective in providing topographic measurements critically important to the understanding of the formation and early evolution of planetary bodies. Using laser altimetry data, topographic grids can be produced that provide significant insight into the shape, internal structure and evolution of the subject body.

Abstract : Using altimeter data for quantitative information about sea ice is an idea with relatively few proponents. Often the poor spatial sampling given by the altimeter's single-point measurements along widely spaced ground tracks and the difficulty of interpreting altimeter pulse echoes over ice are cited as reasons to avoid altimetry.

Lakes Studies from Satellite Altimetry
2010Accurate and continuous monitoring of lakes and inland seas has been possible since 1993 thanks to the success of satellite altimetry missions: TOPEX/POSEIDON (T/P), GFO, JASON-1, and ENVISAT. Global processing of the data of these satellites can provide time series of lake surface heights over the entire Earth at different temporal and spatial scales ...
