The research on RTM of bathymetry estimation in airborne gravity data downward continuation
2010 Sixth International Conference on Natural Computation, 2010The RTM of bathymetry is introduced in the remove-restore technique in order to construct high accuracy marine gravity map. Based on the relationship between the bathymetry and the gravity anomaly, the bathymetry model is used to study the effect of the bathymetry to the marine gravity anomaly.

Adaptive wave tracing for coastal bathymetry estimation
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Wave-based estimation of coastal bathymetry from satellite images is challenging because it often implies relying on ancillary data. Moreover, spatial resolution remains coarse compared to the image resolution because state-of-the-art wave analysis techniques decompose images into large-size patches.

Rapid estimation of bathymetry from multispectral imagery without in situ bathymetry data
Applied Optics, 2019Optimization-based semi-analytical methods (OSMs) and empirical methods (EMs) have been developed to derive bathymetry maps from satellite-based multispectral data of coral reefs, allowing for the management, monitoring, and protection of coral reefs.

Synthetic aperture bathymetry estimation with a multielement array
Proceedings of the 27th Conference on Image and Vision Computing New Zealand, 2012Bathymetric estimation from multiple synthetic aperture sonar (SAS) images is challenging for shallow water environments with low frequencies. This is due to the multipath echoes corrupting the desired direct-path echoes. In an attempt to suppress some of these multipaths, the MUD synthetic aperture sonar developed at TNO has a sixteen element vertical

A new python tool for coastal bathymetry estimation : S2Shores
2023        Coastal areas host 53% of the world's population increasingly subject to risks related to climate change. In order to understand and prevent these risks, the prediction of coastal hydrodynamic and morphological evolution is essential.

Interferometric angle estimation for bathymetry performance analysis
OCEANS 2011 IEEE - Spain, 2011The quality of depth measurements used in either sonar or radar applications determines the confidence on the mapping accuracy. Several methods can be considered to determine this depth measurement, ranging from amplitude-based detection, interferometry, to complex signal-based detection, such as so-called high-resolution methods. This paper is devoted

Geostatistical Gravity Inversion for Estimating Sub-Ice-Bathymetry
2022<p>Sub-ice-bathymetry is an important boundary condition when modelling the evolution of ice shelves and ice sheets. Radar sounding is a proven method to reveal the sub-ice-topography beneath grounded ice. However, it fails to image the bathymetry beneath the floating ice shelves due to the strong radar reflectivity of sea water.

Estimating near-shore bathymetry using SAR
IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998Presents two algorithms for estimating near-shore bathymetry from synthetic aperture radar (SAR) data. The first algorithm utilizes the kinematics of the shoaling waves to extract depths under the assumption of no significant current in the direction of wave propagation. The second algorithm utilizes the average radar cross section to estimate the rate

Backscatter Features for Estimating Synthetic Aperture Sonar Bathymetry
Global Oceans 2020: Singapore – U.S. Gulf Coast, 2020Synthetic aperture sonar (SAS) bathymetric mapping has matured in recent years and is adopted by industry, government and academia for mapping and exploration of large areas in more detail than previously feasible. As with other types of bathymetric mapping, averaging is often a critical processing step in order to gain sufficient signal quality to ...
