Nonlinear Ship Wake Detection in SAR Images Based on Electromagnetic Scattering Model and YOLOv5

Remote Sensing, 2022
Traditional wake detection methods have been successfully applied to the detection of a simple linear ship wake. However, they cannot effectively detect nonlinear wake and weak wake under high sea state conditions, whereas the deep-learning-based ...

Study on Ship Kelvin Wake Detection in Numerically Simulated SAR Images

Remote Sensing, 2023
To improve ship safety and increase ship concealment, we introduce a nonconvex regularization with a Cauchy-based penalty for discussing the influence of ship parameters and speckle noise in numerically simulated SAR images.

A Novel Data-Driven Scheme for the Ship Wake Identification on the 2-D Dynamic Sea Surface

IEEE Access, 2020
Because the ship wake spreads into an area much larger than that of the ship hull in the sea surface, it has been widely used in the ship detection. However, due to the complex sea wave motion and the high sea state, the ship wake detection is still a ...

Nominal vs. Effective Wake Fields and Their Influence on Propeller Cavitation Performance [PDF]

Journal of Marine Science and Engineering, 2018
Propeller designers often need to base their design on the nominal model scale wake distribution because the effective full scale distribution is not available.

Pre-Processing of Simulated Synthetic Aperture Radar Image Scenes Using Polarimetric Enhancement for Improved Ship Wake Detection

Remote Sensing
Ship wake detection using synthetic aperture radar (SAR) imagery provides a way to obtain small marine ship information, but it often becomes unavailable and unreliable during a high sea state.

Ship Wake Detection in SAR Images via Sparse Regularization [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2019
In order to analyse synthetic aperture radar (SAR) images of the sea surface, ship wake detection is essential for extracting information on the wake generating vessels.

Non-Linear Modeling of Detectability of Ship Wake Components in Dependency to Influencing Parameters Using Spaceborne X-Band SAR

Remote Sensing, 2021
The detection of the wakes of moving ships in Synthetic Aperture Radar (SAR) imagery requires the presence of wake signatures, which are sufficiently distinctive from the ocean background.

Ship detection and classification based on cascaded detection of hull and wake from optical satellite remote sensing imagery

GIScience & Remote Sensing, 2023
Satellite remote-sensing provides a cost- and time-effective tool for ship monitoring at sea. Most existing approaches focused on extraction of ship locations using either hull or wake.

A New Automated Ship Wake Detector for Small and Go-Fast Ships in Sentinel-1 Imagery

Remote Sensing, 2022
In the field of maritime surveillance with satellite imagery, ship detection with Synthetic Aperture Radar (SAR) is largely successful with the exception of those cases where the target Radar Cross Section (RCS) results very low and hard to detect.
