Basic Radar Altimetry Toolbox & Tutorial
The Basic Radar Altimetry Toolbox is a collection of tools, tutorials and documents designed to facilitate the use of radar altimetry data. It is able to read most distributed radar altimetry data, from ERS-1 & 2, Topex/Poseidon, Geosat Follow-on, Jason-1 and 2, Envisat, and the future Cryosat mission, to perform some processing, data editing and statistic, and to visualise the results. As part...
متن کاملGlobal Inland Water Monitoring from Satellite Radar Altimetry – a Glimpse into the Future
The capability of satellite radar altimeters to monitor the height changes of major lakes is well established. However, river systems present far more challenging targets. By retracking altimeter echoes using an expert system approach, river heights can be successfully monitored; this capability is bounded by the along-track sampling rate. However, a glimpse into the potential of future altimet...
متن کاملSensitivity Analysis of Brown Model Waveform in Radar Altimetry
In satellite altimetry (radar altimetry), the altimeter emits a pulse, with known power, to the earth surface and receives it back continuously to determine of the sea surface height. The time series of the mean returned power is recorded individually at satellite as the so-called waveform. Analytical model for the waveform is first introduced by Brown, which consists of six parameters: signif...
متن کاملRadar Altimetry of Mercury' A Preliminary Analysis
Measurements of Mercurian topography based on Arecibo radar observations are presented. The data, which were obtained from 1978 to 1984, cover much of the equatorial zone of Mercury between 12øN and 5øS latitude. Over thirty continuous altitude profiles were obtained, each spanning from 20 to 90 degrees of longitude at a resolution of 0.15 ø (longitude) by 2.5 ø (latitude). Radar depths for lar...
متن کاملIce Measurements by Geosat Radar Altimetry
The surface topography of the Greenland and Antarctic ice sheets is the principal ice parameter obtainable from satellite radar altimetry. The improved ability of the GEOSA T altimeter to follow irregular surfaces and its extended operation have greatly increased the available topographic data on ice sheets for the study of ice dynamics and the possible detection of changes in global ice volume.
