Timing and Synchronization

The WIS network will consist of digital access and nodal switches interconnected by time division multiplexed and bulk encrypted links. Timing and Synchronization (T & S) functions are therefore of vital importance for WIS. The synchronization concept must define the technical criteria to distribute and maintain permitted timing relationships at the WIS witching, transmission and terminal elements.

Planning and Architectural Design of Integrated Services Digital Networks

Planning and Architectural Design of Integrated Services Digital Networks: Civil and Military Applications provides a comprehensive treatment of ISDNs: how to plan and design them architecturally and how to implement them so that they meet certain given user requirements ranging from a variety of service demands to transmission performance, security, reliability/availability, capability for growth, interoperability with other ISDN and non-ISDN networks and, of course, cost. The book concentrates on the application of ISDN concepts and standards to the planning and design of real costed networks to meet certain specified user requirements. Where there are multiple options, considerations and rationale on the choice of network aspects and standards are discussed. The unique feature of the book, compared with other books on ISDN, is that it expounds an original methodology which starts from an assumed or given set of complete user requirements and proceeds to designing a complete network taking into account the technology and standards of ISDN, as well as some constraints including cost which may be imposed. Planning and Architectural Design of Integrated Services Digital Networks describes computer-aided design tools employed for dimensioning the network for various traffic loads and for assessing its traffic carrying performance for assessing different precedence categories and network configurations, transmission conditions and routing algorithms which may be static-deterministic or dynamic-adaptive. Aspects such as surveillance and control, security, survivability and EMP protection are also addressed. Planning and Architectural Design of Integrated Services Digital Networks: Civil and Military Applications is an excellent reference source and may be used as a text for advanced courses on the subject.

Switching and Signalling

At the outset of the WIS System Design study it become apparent that the WIS switching subsystem must satisfy communications requirements arising from the functions of its individual users in war and peacetime conditions as well as in periods of crises. The switching system concept was therefore developed by taking into consideration the operational and performance requirements of the WIS network and services. The WIS network is conceived to be based on a common user, basically circuit switched, area grid network, providing situation oriented, low delay, voice and non-voice services, supporting packet and message switches, and capable of accommodating evolutionary trends in services.

Simulation of Maritime Surveillance Systems

This chapter is about techniques for using computers to imitate, or simulate, the operations of various kinds of real world maritime surveillance facilities and processes. The contents of the chapter is organized as follows:

Multisensor Data Fusion

The main objective of multisensor data fusion is to combine elements of raw data from multiple sensors to extract the greatest amount of information possible about the sensed environment which is greater than the sum of its contributing parts. In the literal sense, data refers to the actual measurements taken or information obtained by the sensors and fusion is the process of combining the data or information in such a way that the results provide more information than the sum of the individual parts [7.1, 7.4].

Cost Analysis and Implementation Planning

The acceptability or feasibility of any system design would depend, to a large extent, on its cost and affordability and this requires an estimation to be made of the cost of all the subsystem/components of the total system. Cost estimation is often done in two steps which we may call type-A and type-B. The type-B cost estimate of the final system design to be implemented would be required to be as accurate as possible, say ± 10%, for budgeting purposes. When different system options are being evaluated for cost-effectiveness, more easily available and perhaps less accurate price information (type-A estimates), say ± 25%, would be adequate.

Principles of Automatic Target Recognition in a Maritime Environment

In this chapter the problems related to the “recognition” of vessels in a maritime surveillance area will be discussed. In the context of this chapter “recognition” will be used as a generic term which includes both “classification” and “identification” activities. The main problematic area is the recognition by machines of noncooperative vessels using microwave radars; this is the main topic of this chapter.
