Evolution of the Satellite Radar Altimeter
The radar altimeters flown on Geos-3 (1975), Seasat-l (1978), and Geosat-l (1985) have amply demonstrated the benefits of high-precision measurements of ocean-surface topography, both to geodesy and to oceanography. Two new altimetry missions are planned: the joint NASA/Centre National d'Etudes Spatiales TOPEx/Poseidon mission, to be launched in 1992, and the Navy's Special Purpose Inexpensive ...
متن کاملThe Envisat Radar Altimeter System (RA-2)
The mission RA-2 has an essential role to play in the Envisat mission, as indicated in Table 1. Operating over oceans, its data can be used to monitor seasurface topography, thereby supporting research into ocean circulation and sea-level change, as well as providing observations of the sea floor structure or shape, and marine geoid characteristics. It will also be possible to determine near-se...
متن کاملCramér-Rao bounds for radar altimeter waveforms
The pseudo maximum likelihood estimator allows one to estimate the unknown parameters of Brown’s model for altimeter waveforms. However, the optimality of this estimator, for instance in terms of minimizing the mean square errors of the unknown parameters is not guarantied. Thus it is not clear whether there is some space for developing new estimators for the unknown parameters of altimetric si...
متن کاملICESat laser altimeter measurement time validation system
NASA launched its Ice, Cloud and Land Elevation Satellite (ICESat) in January 2003. The primary goal of this laser altimeter mission is to provide determination of volumetric changes in the ice sheets, specifically in Antarctica and Greenland. The instrument performance requirements are driven by the scientific goal of determining a change in elevation on the centimetre level over the course of...
