Highlight
• In the past, the main goals of Synthetic Aperture Radar (SAR) systems were the study of the interaction of electromagnetic waves with the earth surface.

• Recently, the development of multi-channel SAR systems has enabled the development of more sophisticated techniques for the surveillance activities.

• SAR is the most efficient instrument, which provides high-resolution data for wide ocean area surveillance under all weather conditions. The intrinsic capability of this instrument is to provide a quick view of the oceanic surface features such as vessels, waves and currents, oil spills, laver facilities and wind fields.

• The ship detection/recognition is achieved in two steps: the first step is to identify the ship in SAR images of a busy traffic, which corresponds to Automatic Identification System (AIS) signals by the “dead-reckoning (DR) position”, and the second step is to estimate the position, size and speed of the ship from SAR images and compare these results with the AIS “true” data.

Abstract
In the past, the main goals of Synthetic Aperture Radar (SAR) systems were the study of the interaction of electromagnetic waves with the earth surface. Recently, the development of multi-channel SAR systems has enabled the development of more sophisticated techniques for the surveillance activities. SAR is the most efficient instrument, which provides high-resolution data for wide ocean area surveillance under all weather conditions. The intrinsic capability of this instrument is to provide a quick view of the oceanic surface features such as vessels, waves and currents, oil spills, laver facilities and wind fields. The ship detection or recognition is achieved in two steps: the first step is to identify the target in SAR images of a busy traffic, which corresponds to Automatic Identification System (AIS) signals by the “dead-reckoning (DR) position”, and the second step is to estimate the position, size and speed of the ship from SAR images and compare these results with the AIS “true” data. This paper presents the fundamentals of SAR and its integration with the AIS data for the ship target detection.

These days one can effectively track and monitor everything that one wishes to. A vessel tracking system, as the name suggests is a collection of equipments which enable marine and naval vessels to track, identify and monitor a ship’s position, location and any other detail that might be important in maneuvering and stabilizing a ship’s route and course.

Methodology Article First Online: 05 November 2018

Abstract

Maritime Border Collision is one of the vital concerns in coastal states since the maritime boundaries of any two countries cannot be identified easily during fishing.

Maritime domain awareness and the border line control are the essential requirement which happens via recognition, and observing of boats inside their country boundary.

It is necessary to identify the maritime border and alert the fisherman during the fishing.

Received: 30 October 2018 / Revised: 10 March 2019 / Accepted: 11 March 2019 / Published: 15 March 2019

Abstract
In order to monitor and manage vessels in channels effectively, identification and tracking are very necessary.

This work developed a maritime unmanned aerial vehicle (Mar-UAV) system equipped with a high-resolution camera and an Automatic Identification System (AIS).

A multi-feature and multi-level matching algorithm using the spatiotemporal characteristics of aerial images and AIS information was proposed to detect and identify field vessels.

The Spree-Oder Waterway (SOW) is to become a digital testing ground for autonomous and automated inland navigation. From July, a project Autonom-SOW with partners from industry, federal government and science, said the Federal Association of Public Inland Ports (BÖB) on Friday. After initial investigations, construction is to begin in 2020. The test field at the SOW is one of four projects under the action plan “Digitalisation and Artificial Intelligence in Mobility” of the Federal Ministry of Transport.

The rapid advancement of technology has significantly improved the methods of monitoring and tracking the ships in the recent past. The fast-developing satellite services have enabled the ship tracking across the globe easier now and thus ensuring the safety of vessels from various threats.

With the help of satellite-based vessel monitoring systems (VMS), different types of vessels have been monitoring efficiently by marine agencies and vessel owners for a long period. The automatic identification system (AIS) helps track bigger vessels crossing waters across the world by offering real-time information about the vessels.
