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.

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 ...

Sea Trials of the SWATH Ship USNS Victorious (T-AGOS 19)

Marine Technology and SNAME News, 1994
In 1986 the design of the Navy's first large SWATH (small waterplane area twin hull) ship was completed. Designated the T-AGOS 19 Class, these vessels were designed to operate comfortably in high latitudes during winter months. The T-AGOS 19 and T-AGOS 23 Classes represent one of the greatest departures in naval surface ship design in the past century.

Ultra Wide Swath Deep Sea Interferometric Multibeam Echo Sounder With Sea Bottom Imaging System

Conference Proceedings on Engineering in the Ocean Environment, 2005
The SIMRAD EM12 is a new full ocean depth multibeam echo sounder, operating at 13 kHz. By use of interf erometric signal processing techniques it will acheive an ultra wide swath geometry of 150 degrees, corresponding to 7 . 5 times the depth of water.

Measurements during SWATH ship sea trials

IEEE Instrumentation & Measurement Magazine, 2000
A new ship must undergo a rigorous set of sea trials to receive final certification. The sea trials program measures the vessel's performance against its design specifications and code requirements. The performance evaluation includes the ship's powering requirements (ability to achieve and maintain its design speed in a variety of conditions), fuel ...

Characterization of the ocean waves signature to assess the Sea State Bias in wide-swath interferometric altimetry

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
Ahstract-A comprehensive description of the Sea State Bias (SSB) for wide-swath interferometric (WSI) altimetry is proposed using a two-scale transfer function of the first-of-its-kind instrument, the KaRIn instrument of the SWOT mission. We show that the SSB encompass the contribution of the ElectroMagnetic Bias (EMB) similarly to conventionnal ...

Sub-daily Antarctic sea-ice variability estimates using swath-based retrieval methods

2023
Satellite-derived sea-ice concentration measurements have traditionally been used to evaluate the impact of climate change on polar regions. However, concentration-based measurements of sea-ice variability do not allow the discrimination of the relative contributions made by thermodynamic and dynamic processes.

Theoretical Modeling of Sea-State Bias in Interferometric Wide-Swath Altimetry

IEEE Transactions on Geoscience and Remote Sensing
Sea-state bias (SSB) is an important source of error in nadir altimetry. Here, we focus on understanding from first principles how SSB will affect measurements over the ocean from the new interferometric swath altimeter KaRIn, on-board the Surface Water Ocean Topography (SWOT) mission.

Submarine landslide origin of a tsunami at the Black Sea coast: Evidence based on swath bathymetry and 3D seismic reflection data

Interpretation, 2021
Tsunami waves were observed along the Bulgarian Black Sea coastline on 7 May 2007. The maximum rise and fall of the sea level were 1.2 and 2.0 m, respectively, with wave oscillations between 4 and 8 min. At first, submarine landsliding and then later on atmospheric disturbance were suggested as the cause of the tsunami.
