Ship Detection in SAR Imagery
Abstract---As a part of Maritime Domain Awareness, there is a requirement to detect ships in satellite-borne Synthetic Aperture Radar (SAR) images, which provide wide area ocean surveillance. When ship detection is implemented using a Constant False Alarm Rate (CFAR), statistical theory can be employed to ensure that proper parameters are used to find the thresholds for detection; inaccuracy ...
متن کاملAn Adaptive Ship Detection Scheme for Spaceborne SAR Imagery
With the rapid development of spaceborne synthetic aperture radar (SAR) and the increasing need of ship detection, research on adaptive ship detection in spaceborne SAR imagery is of great importance. Focusing on practical problems of ship detection, this paper presents a highly adaptive ship detection scheme for spaceborne SAR imagery. It is able to process a wide range of sensors, imaging mod...
متن کاملA Novel Algorithm for Ship Detection in Envisat Sar Imagery Based on the Wavelet Transform
Carrying out an effective control of fishing activities is essential to guarantee a sustainable exploitation of sea resources. While traditional reconnaissance methods, such as planes and patrol vessels are indispensible, their operation is quite time consuming and costly over the extended regulated areas. On the contrary, satellitebased Synthetic Aperture Radar (SAR) provides a powerful survei...
متن کاملAutomatic Ship Detection in Space-borne Sar Imagery
Synthetic aperture radar (SAR) imagery has proven to be a promising data source for the surveillance of maritime activity, and its application for automatic ship detection has been the focus of many research studies. Apart from the well-known CFAR detector, there has emerged a novel method for automatic ship detection, based on the wavelet transform. Since the underlying principles for both met...
متن کاملAn Automatic Ship Detection Method Based on Local Gray-Level Gathering Characteristics in SAR Imagery
This paper proposes an automatic ship detection method based on gray-level gathering characteristics of synthetic aperture radar (SAR) imagery. The method does not require any prior knowledge about ships and background observation. It uses a novel local gray-level gathering degree (LGGD) to characterize the spatial intensity distribution of SAR image, and then an adaptive-like LGGD thresholding...
