Distributed Sensor Arrays ─ Localization

Localization of transmitters and receiving sensors is achieved by measuring radiation emitted by a source to a set of sensors, which are either on a definite pattern known as array or randomly located at irregular points known as distributed sensor array. This book discusses how to determine the position of sensors and transmit information to a central node, also known as the anchor node. Time of arrival, time difference of arrival, frequency time of arrival, and strength of received signal will be covered. Effective algorithms and implementation as well as numerical examples are included. Time synchronization, including the rotating laser beam to measure distance, is discussed in detail.

Prabhakar S. Naidu obtained a Bachelor of Science and Master of Technology from the Indian Institute of Technology, Kharagapur, followed by a Ph.D. from UBC, Canada. He worked for nearly 30 years at the Indian Institute of Science in Bangalore as a Professor in the department of Electrical and Communication Engineering. In 1965 he was awarded NRC (Canada) fellowship, followed by the Alexander von Humboldt Fellowship. He holds a Senior Research Associateship from NRC (USA) and is listed in Marquis’ 17th Edition of “Who's Who in the World”. Dr. Naidu has also worked as a visiting Scientist at the Australian Telecommunication Research Center. His research interests include array signal processing, spectrum analysis of time series, and geophyical signal processing.
