An Innovative Approach for the Calibration of Wide Swath Altimeters

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Wide Swath altimetry can produce high resolution images of global water surface height rapidly, and would play an important role in oceanography and hydrology. However, the sea surface height error is extremely sensitive to the roll angle of the platform. In this paper, an innovative approach to calibrate the roll-induced height error is proposed.

Model functions for retrieving sea surface wind speed with wide-swath imaging altimeter

Journal of Applied Remote Sensing, 2021
Using satellite remote sensing technology to observe sea surface wind fields has become an important instrument. The successful launch of Tiangong-2, the future Surface Water and Ocean Topography (SWOT) mission, and demonstrating GaoFen Project provides the future understanding for the generation of new wide-swath imaging altimeter.

Wide Swath Ocean Topography Mapping With Interferometric Altimeters

12th Canadian Symposium on Remote Sensing Geoscience and Remote Sensing Symposium,, 2005
An interferometric radar altimeter is proposed to provide wide-swath high-resolution ocean topography. Several system design issues of such an interferometric altimeter are presented. Tradeoffs between processing of the interferometric signal using the so-called amplitude approach and the so-called phase approach are shown.

Centimetric sea surface height accuracy using the Wide-Swath Ocean altimeter

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
In this paper, we present error sources and predicted performance of the Wide-Swath Ocean altimeter, an instrument which has been proposed as an experiment for the NASA/CNES Ocean Surface Topography Mission. The data obtained by this instrument will allow the detailed study of ocean mesoscale phenomena, with a space-time resolution which cannot be ...

Wide swath SAR and radar altimeter

1993 IEEE Aerospace Applications Conference Digest, 2002
The conceptual design and a spaceborne, high-resolution, wide-swath synthetic aperture radar (SAR) and radar altimeter that can be implemented in L, C or X-band or in a combination of bands is described. The design uses active planar array antennas to form multiple independent beams that cover swaths of up to 700 km.

Analysis on the Accuracy of Marine Gravity Inversion from the Wide-swath Altimeter Mission

2020
<p>Marine gravity is mainly inversed by the nadir satellite altimetry observations. However, the accuracy of the east-west component of vertical deflection is significantly lower than the north-south component. The wide-swath altimeter is one of the main altimetry missions in the future.

The wide swath ocean altimeter: radar interferometry for global ocean mapping with centimetric accuracy

Proceedings, IEEE Aerospace Conference, 2003
The recent Shuttle Radar Topography Mission (SRTM) has demonstrated the capability for global interferometric topographic mapping with meter level accuracy and 30 meter spatial resolution. The next challenge in radar interferometry is the measurement of ocean topography: the global characterization of ocean mesoscale eddies requires global coverage ...

4DVAR Assimilation of simulated wide-swath altimeter data into a high resolution ocean model

2018
Abstract: this study examines the contribution of high resolution altimeter SSH observations from SWOT to the accuracy of the analysis and forecasting of a high resolution ocean model. Current altimeter data sampling of the ocean sea surface height is significantly limited in spatial density.
