SAR Imaging of Ship Wakes and Inverse Ship Wake Problem
نویسندگان
چکیده
Airborne Synthetic Aperture Radar (SAR) images of sea surface often reveal ship wakes, which appear in a form of bright and dark streaks. It is believed that some of them pertain to the ship generated Kelvin wave system and some to the ship turbulent wake (Reed et al., 1990). The streaks in SAR images are sufficiently narrow to consider them as straight segments. Assuming that the location and orientation of the straight segments representing the ship wake in SAR images are defined, a related question arises: do these images contain sufficient information to extract from it certain ship characteristics, e.g. its speed and some principal geometric parameters?

Sonar Measurements in Ship Wakes Synchronous with Terrasar-x Overpasses
A pilot experiment was conducted by NSUOC and DLR in April-June 2008 in the Straits of Florida near Port Everglades, Florida in order to study the dynamics of far wakes of ships. In this experiment, a small boat with downward-looking sonar made “snake-like” sections through wakes of ships of opportunity during the TerraSAR-X overpasses. The ship identity and its parameters (length, speed, cours...
متن کاملApplication of Facet Scattering Model in SAR Imaging of Sea Surface Waves with Kelvin Wake
The principal purpose of this work is the simulation of the ship wake in Synthetic Aperture Radar (SAR) imaging based on a facet scattering model. The hydrodynamic model of the surface waves mainly considers the Kelvin wake waves and the wind driven waves. For the prediction of radar returns from the composite surface, the semi-deterministic facet scattering model (SDFSM) is proposed, which is ...
متن کاملWake Component Detection in X-Band SAR Images for Ship Heading and Velocity Estimation
A new algorithm for ship wake detection is developed with the aim of ship heading and velocity estimation. It exploits the Radon transform and utilizes merit indexes in the intensity domain to validate the detected linear features as real components of the ship wake. Finally, ship velocity is estimated by state-of-the-art techniques of azimuth shift and Kelvin arm wavelength. The algorithm is a...

This paper focuses on the feature analysis of moving ships in synthetic aperture radar (SAR) images and proposes a detection algorithm for ships. The algorithm first detects all the candidate ships and provides analysis of structural features with the discrete topology. In the analysis of structural features, aspect ratio and ship’s navigation direction can be used to construct feature confiden...
متن کاملEstimation of Ship Velocity by Using Sar Imagery - Simulation Methods
The estimation of ship heading and speed from a high resolution Synthetic Aperture Radar (SAR) image of ship and its wake is important for monitoring and tracking ships. In order to get a correct and focused image of the moving ships, it is necessary to know the real positions and velocities of the ships. Though the ship can often be imaged clearly, its orientation may be difficult to estimate ...
