Ship wake detection in SAR images: a segmentation-based approach

IEEE International Geoscience and Remote Sensing Symposium, 2003
This paper deals with the derivation of a fully automatic and reliable ship wake detector (SWD), which can operate in conjunction with a ship detector scheme (SD) for ship traffic control against non-homogeneous sea background in SAR images. A novel segmentation-based technique is introduced for ship wake detection, which overcomes the drawbacks ...

An entropy-based approach to wake echo analysis [ship wake radar detection]

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
This paper addresses the problem of ship wake detection and analysis at low grazing angles using eigenvalue analysis of the covariance matrix. Polarimetric measurements of the wake produced by a pilot boat operating in Port Phillip Bay were obtained using the Defence Science and Technology Organisation's (DSTO) high resolution radar system.

Wake2Wake: Feature-Guided Self-Supervised Wave Suppression Method for SAR Ship Wake Detection

IEEE Transactions on Geoscience and Remote Sensing
Sea clutter and inherent speckle noise in synthetic aperture radar (SAR) images can pose challenges to accurate sea surface target detection, especially for phenomena such as ship wakes reliant on efficient feature extraction.

A Ship Wake Detection Method in SAR Images Based on Joint Sparse Representation

IEEE International Geoscience and Remote Sensing Symposium
The strong sea clutter and noise in synthetic aperture radar (SAR) images will cover weak ship wakes, making it difficult for conventional ship wake detection methods to accurately detect ship wakes.

Robust Wake Detection for Enhanced Maritime Monitoring: Transfer Learning Through a Dedicated Multispectral Ship Wake Data Set

IEEE Journal of Oceanic Engineering
Ship detection has been a topic of great interest since the development of the first remote sensing techniques. The wake generated by moving ships is rich in information regarding the vessel and their instantaneous state. This article tackles the problem

UEIKAP: space-based ship wake detection integrating contextual meteo-marine knowledge of local sea state

Environmental Remote Sensing
Monitoring uncooperative vessels without transponders is of strategical interest both for the civil and military world. Ship detection lacks the ability to discern full situational knowledge of the vessel.

Ship Wake Detection in X-band SAR Images Using Sparse GMC Regularization

IEEE International Conference on Acoustics, Speech, and Signal Processing, 2019
Ship wakes have crucial importance in the analysis of SAR images of the sea surface due to the information they carry about vessels. Since ship wakes mostly appear as lines in SAR images, line detection methods have been widely used for their ...

A novel radon transform-based method for ship wake detection

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Based on the gliding-box algorithm and the Radon transform algorithm, a novel method for detecting ship wakes in synthetic aperture radar (SAR) images is proposed. The method is applied to both simulation images and real SAR image, and the result shows that the detection accuracy is satisfactory in strong noise environment.
