Approximate ship wake solution for fast computation

Ocean Engineering, 2021
Abstract An approximate ship wake solution that accurately predicts both the wake patterns and the wake amplitudes in any water depth is proposed and validated. Derivation based on the small-amplitude wave theory is first revisited, treating a ship as a moving pressure field acting on the water surface. For ship shapes symmetric about the transverse (

Rethinking Automatic Ship Wake Detection: State-of-the-Art CNN-Based Wake Detection via Optical Images

IEEE Transactions on Geoscience and Remote Sensing, 2022
Most existing wake detection algorithms use Radon transform (RT) due to the long streak features of ship wakes in synthetic aperture radar images. The high false alarm rate of RT requires that the algorithms have significant human intervention for image ...

A Method of Ship Wake Detection in SAR Images Based on Reconstruction Features and Anomaly Detector

IEEE International Geoscience and Remote Sensing Symposium, 2023
An anomaly-detection-based method is proposed to improve the performance of ship wake detection in synthetic aperture radar (SAR) images of different sea states. The dictionaries learned by sea clutter images are poor to sparsely reconstruct wake images,
