An Innovative Approach for the Calibration of Wide Swath Altimeters
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Wide 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.

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), 2004In 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, 2002The 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.

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 ...

The wide-swath altimeter uses interferometric synthetic aperture radar technology to obtain a wide-swath detection capability. Referable to the slow undulation of the ocean surface, flat-earth phase is dominant in the interferometric, and the interferometric phase after flat-earth phase removal can reflect the ocean surface elevation change.

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.
