This book was released on 2017 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, environmental and socio-economic factors have generated interest on the observation of the ocean. Thus, the monitoring of maritime human activity has become crucial for the protection of the marine environment, the sustainability of the industrial sector, and security of navigation. Spaceborne remote sensing technologies can be used to improve existing marine monitoring systems at a global level. In particular, the Synthetic Aperture Radar (SAR) spaceborne sensors offer significant advantages for global monitoring. These types of sensors acquire high-resolution radar images suitable for the identification of man-made objects such as artificial structures and vehicles. In addition, these images can be obtained from any part of the planet's surface with no need for natural illumination, and practically regardless of the weather conditions over the area of interest. The current spaceborne SAR sensors have the potential to complement traditional maritime monitoring systems by acting as an independent source of information for the detection and identification of presumed vessels. This research focuses on the analysis of the characteristics of maritime SAR images from spaceborne sensors, the improvement of simulation tools, and the development and evaluation of algorithms for extracting information of interest which can be applied to vessel monitoring. In particular, it takes the case of stripmap SAR single-look complex (SLC) images since this is the most basic SAR product that all of the current spaceborne sensors are capable of providing. Theoretical analysis and evaluation of simulations establish, firstly, the relation between the motions of the vessels and phase errors in their received SAR signals, and secondly, how these phase errors impact on the position and focus quality of the vessels¿ SAR signatures in the image. In this thesis, the defocus of the targets is identified as one of the factors that hinders the proper extraction of the characteristics of vessels from the shape of their SAR signature. Thus, this thesis proposes local application of classical autofocus techniques adapted to the case of stripmap SLC images, and evaluates their performance using simulated data and real images of vessels from sensors such as RADARSAT-2 and Cosmo-SkyMed. Moreover, by analysing the SAR signal of the vessels in both the image and Doppler domain, techniques for automatic extraction of features of the SAR signatures such as size, direction, range velocity component, and basic identification of the type of vessel are proposed. Finally, all these techniques are merged into a single postprocessing sequence, which this thesis proposes as an algorithm for automatic refocusing and feature extraction of detected vessels in stripmap SLC SAR images. The evaluation and analysis of the performance of this algorithm with RADARSAT-2 and Cosmo-SkyMed images suggest its potential use in operational applications, although as in the case of other vessel identification algorithms, its performance is dependent on the complexity of the SAR signatures of the vessels.

Available in PDF, EPUB and Kindle. Book excerpt: International Maritime Security Law by James Kraska and Raul Pedrozo defines an emerging interdisciplinary field of law and policy comprised of norms, legal regimes, and rules to address today's hybrid threats to the global order of the oceans. Worldwide shipping commerce, fishing fleets, pleasure craft, and coastal states are exposed to the menace of offshore terrorism, weapons of mass destruction, piracy, smuggling, robbery, marine insurgency and anti-access threats. Land-based institutions and maritime constabulary forces operate within an increasingly integrated network that blends elements of humanitarian law, human rights law, criminal law, and law of the sea, with inspection regimes, commercial enterprise, and marine safety and environmental stewardship. The new authorities fuse together a global maritime partnership among states, international organizations and commercial interests to protect the maritime commons from the most dangerous risks and hazards.
