Instructor:

Richard G. Wiley, Ph. D. has worked in ELINT since the 1960s. He has published 5 books, including the textbook for this course, as well as may technical papers. His accomplishments include the first fielded computer based TOA system and the first receiver specifically designed to intercept LPI radar signals. He was co founder of Research Associates of Syracuse which provides technical solutions for today's ELINT environment.
