Radar Altimetry and Acoustic Prediction

1991
An evaluation of the PARQUES acoustic propagation model to take into account the oceanic mesoscale variability as observed during the ATHENA experiment and an assessment of the GEOSAT altimeter for observing this variability and predict acoustic propagation are presented. The ATHENA experiment took place in summer 1988 in the north East Atlantic around

Open Source Visualization for Radar Altimetry Waveforms

2021 IEEE 19th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2021
Radar altimetry is a valuable tool for monitoring topographic changes in Earth’s polar regions. An important part of these altimetry data sets is the waveforms that are received and recorded by the radar. These waveforms are processed to create surface-height data products, but also contain information about the scattering surface and near-subsurface ...

Broadview radar altimetry toolbox

2016
The universal altimetry toolbox, BRAT (Broadview Radar Altimetry Toolbox) which can read all previous and current altimetry missions’ data, incorporates now the capability to read the upcoming Sentinel-3 L1 and L2 products. ESA endeavoured to develop and supply this capability to support the users of the future Sentinel-3 SAR Altimetry Mission. BRAT is

Radar altimetry of South Tharsis, Mars

Icarus, 1980
The paper discusses Martian altitudes measured by radar during the oppositions of 1971 and 1973 using the 64-m antenna at Goldstone, Calif. The resultant topographic profiles substantiate a zonal classification of the volanic flows blanketing the south flanks of Arsia Mons, and they confirm the existence of a secondary, parasitic shield, attached from ...

Radar altimetry of large Martian craters

Icarus, 1989
A total of 108 13-cm wavelength scans conducted for the 23 to -22 deg latitude regions of Mars during the 1971-1982 oppositions are of sufficiently high resolution to allow elevation differences of as much as 3 km over less than 10 deg longitude to be observed; most of this local relief is furnished by structural elements of impact craters.

Measurements of electromagnetic bias in radar altimetry

Journal of Geophysical Research: Oceans, 1991
The accuracy of satellite altimetric measurements of sea level is limited in part by the influence of ocean waves on the altimeter signal reflected from the sea surface. The difference between the mean reflecting surface and mean sea level is the electromagnetic bias.

Daily River Discharge Estimates by Merging Satellite Optical Sensors and Radar Altimetry Through Artificial Neural Network

IEEE Transactions on Geoscience and Remote Sensing, 2019
Thanks to the large number of satellites, the multimission approach is becoming a viable method to integrate measurements and intensify the number of samples in space and time for monitoring the earth system.

Radar altimetry of Mercury: A Preliminary analysis

Journal of Geophysical Research: Solid Earth, 1986
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 12°N and 5°S latitude. Over thirty continuous altitude profiles were obtained, each spanning from 20 to 90 degrees of longitude at a resolution of 0.15° (longitude)

Radar Altimetry for Land Applications

1989
An international programme for polar earth observations will be established by NASA /ESA/NASDA, starting in 1995. Among many other instruments, the first NASA mission (EOS-1) will possibly incorporate a sensor system for measuring global land topography.
