Choice of Modulation Mode and Satellite-Based Radar Altimeter Parameters

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 ...

Estimation and Analysis of Precipitable Water Vapor Using GPS Data and Satellite Altimeter

Determination of water vapor in the atmosphere plays an important role in forecasting weather conditions and precipitation studies. For this reason, it is very important to study the tropospheric delay, especially the wet component, which is due to the presence of water vapor in the atmosphere. In this paper, the amount of water vapor was estimated by altimeter satellite radiometer and GPS data...

Cramér-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...
