An Evaluation of Current Ship Wake Detection Algorithms in SAR Images

چکیده
SHORT ABSTRACT: Ship wakes are often used as the primary means to detect ships in SAR images since they can extend for kilometers. On radar images, they often take the appearance of bright and/or dark lines hidden in the sea clutter. For this reason, robust and efficient line detection algorithms are needed. Our first results tend to support the classical method relying on the Radon Transform and confirm the improvements brought the recently proposed stochastic matched filtering (proposed in 2005), but are somewhat mitigated about the wavelet correlator (proposed in 2003), the Hough Transform or the use of Wiener filtering to improve the Radon Transform thresholding.

The Extended Sub-look Analysis In Polarimetric SAR Data For Ship Detection
The monitoring of maritime areas with remote sensing is essential for security reasons and also for the conservation of environment. The synthetic aperture radar (SAR) can play an important role in this matter by considering the possibility of acquiring high-resolution images at nighttime and under cloud cover. Recently, the new approaches based on the sub-look analysis for preserving the infor...
متن کاملExtended ratio edge detector for despeckled SAR image evaluation
Synthetic aperture radar (SAR) images due to the usage of coherent imaging systems are affected by speckle. So lots of despeckling filters have been introduced up to now to suppress the speckle. Hence, objective and subjective evaluation of the denoised SAR images becomes a necessity. Thereby lots of objective evaluating estimators are introduced to evaluate the performance of despeckling filte...
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 ...
متن کاملSAR Imaging of Ship Wakes and Inverse Ship Wake Problem
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 ...

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...
