Current maritime transportation and shipping is characterized by rapid technological developments effecting the basic concepts of operating ships and even changing traditional paradigms of controlling ships. The e-Navigation concept of the International Maritime Organization (IMO) specifically aims at more comprehensive and reliable support of the human operators on-board and ashore. However, autonomous unmanned ships remote controlled or even autonomously navigating are expected to come soon. In this paper, selected operational aspects of maritime traffic merging conventional and unmanned remote controlled ships in coastal areas are discussed. Furthermore, some preliminary results of experimental simulation studies into a future scenario of maritime traffic are presented and preliminary conclusions in respect to job profiling and training requirements are discussed.

The increasing request for safety, security and environment protection at local and national level reveal the deficiency of the traditional surveillance and control centers to satisfy the needs and requirements of modern border control systems for homeland protection where land border is expected to be monitored as well as the maritime one. This is, for instance, the case of any land border affected by hidden immigration and/or illegal traffics as well as any small areas such as critical infrastructures or military/ civilian posts in forest or jungle environment characterized by vegetation. In such challenging environment, logistics constraints strongly recommend to have very low power devices able to operate months or years without maintenance. A such scenario should be the perfect place for implementing an Unattended Ground Sensors (UGS) network making use FOliage PENetration (FOPEN) radar for border control. The paper aims to present the basic characteristics and preliminary results of a Surveillance Unattended FOPEN (SUF) radar suitable for detecting moving targets, people or vehicles, in dense forest environment.

The International Maritime Organization (IMO) adopted the following definition of e-Navigation: “e-Navigation is the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and relat-ed services, for safety and security at sea and protection of the marine environment”. A pre-requisite for the e-Navigation is a robust electronic positioning system, possibly with redundancy. A new radar technology emerged from the last IALA-AISM conference held in Cape Town, March 2010, where almost all the manu-factures companies involved on navigation surveillance market presented –at various state of development- solid state products for VTS and Aids to Navigation indicating a new trend for this application. The paper present an overview of the systems for global navigation and new trend for navigation aids. The expected de-velopments in this field will also be briefly presented.

In this paper, we address the adaptive detection/classification of signals in a homogenous interference environment. We refer to a radar system equipped with a phased array antenna and account for both the presence of mutual coupling between radiating antennas and a possible coherent interferer impinging on the array mainbeam. To deal with this scenario, we adopt a two-stage detection/classification scheme, enjoying the Costant False Alarm Rate (CFAR) property, to discriminate between target detection and coherent interferer rejection. Finally, we evaluate the system performance via Monte Carlo simulations. The results show that our system has interesting rejection capabilities and satisfactory detection levels. As a consequence, it could be successfully applied in real scenarios where mutual coupling is present.
