Ship Detection with Wireless Sensor Networks
IEEE Transactions on Parallel and Distributed Systems, 2012Surveillance is a critical problem for harbor protection, border control or the security of commercial facilities. The effective protection of vast near-coast sea surfaces and busy harbor areas from intrusions of unauthorized marine vessels, such as pirates smugglers or, illegal fishermen is particularly challenging.

Ship trajectory anomaly detection
Intelligent Data Analysis, 2019This paper compares a number of state-of-the-art anomaly detection methods on real ship trajectories obtained by an Automatic Identification System (AIS) in the Baltic sea. Because most methods need fixed length trajectory representations, the paper also gives some solutions for reducing variable length trajectories to a fixed size.

Ship wake detection by Raman lidar
Applied Optics, 2010We carried out a remote study of ship wakes by optical methods. Both Mie and Raman scattering signals and their evolution were simultaneously recorded by gated detector (intensified CCD). The Mie scattering signal was detectable within 1 min after water disturbance by a high-speed boat.

The ship detection capability of ENVISAT's ASAR
IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004Norway has used spaceborne SAR systems for operational fisheries monitoring since 1998. RADARSAT-1 has been the main source of data. With ENVISAT, there are plans to increase usage of satellite data. First, however, it is important to verify which modes and products are most useful for operational purposes.

GOPCE-Based Approach to Ship Detection
IEEE Geoscience and Remote Sensing Letters, 2012A new approach is proposed for ship detection, based on the generalized optimization of polarimetric contrast enhancement (OPCE). The new approach consists of two steps. For the first step, the OPCE problem will be solved for obtaining optimal polarizations. In this way, the received powers of a sea area are suppressed.

Benchmarking operational SAR ship detection
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004The performances of eight satellite SAR ship detection systems (most of them operational) are compared, by running a benchmark test on RADARSAT images of various modes.

An information system for ship detection and identification
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011We have since last year been designing a ship detection and identification system (SDIS) which aims to contribute to the mitigation of maritime issues that have been increasing in recent years. SDIS will integrate many existing data sources which are readily available either commercially or through partnerships with governmental organizations including
