Ground Based Wireless Positioning provides an in-depth treatment of non-GPS based wireless positioning techniques, with a balance between theory and engineering practice. The book presents the architecture, design and testing of a variety of wireless positioning systems based on the time-of-arrival, signal strength, and angle-of-arrival measurements. These techniques are essential for developing accurate wireless positioning systems which can operate reliably in both indoor and outdoor environments where the Global Positioning System (GPS) proves to be inadequate. The book covers a wide range of issues including radio propagation, parameter identification, statistical signal processing, optimization, and localization in large and multi-hop networks. A comprehensive study on the state-of-the-art techniques and methodologies in wireless positioning and tracking is provided, including anchor-based and anchor-free localisation in wireless sensor networks (WSN). The authors address real world issues such as multipath, non-line-of-sight (NLOS) propagation, accuracy limitations and measurement errors. Presenting the latest advances in the field, Ground Based Wireless Positioning is one of the first books to cover non-GPS based technologies for wireless positioning. It serves as an indispensable reference for researchers and engineers specialising in the fields of localization and tracking, and wireless sensor networks.

This is a research monograph on Fresnel zone antennas. Unlike the conventional reflector and lens antennas, the focusing effect in a Fresnel zone antenna is achieved by controlling the phase shifting property of the surface rather than its shape, thus allowing flat or arbitrary configurations. Other advantages of these include low manufacturing and installation cost and ease of packaging. The material presented is mainly drawn from the theoretical and experimental work published and unpublished by the authors. The book contains a wealth of unusual antenna configurations, first hand experimental results, and a large number of equations useful in the research, analysis and design of Fresnel zone antennas.
