The IEE in association with the IEEE and IERE organised an international specialist seminar on Advanced Signal Processing in Radar, Sonar and Communications, in September 1984. The Seminar was held at the University of Warwick and this book contains a collection of the papers presented. Some of the material is of a tutorial nature while some of it represents the latest state-of-the-art. Inevitably, because signal processing is limited by the components available, the subject matter ranges from the individual components and their impact on signal processing, through to the design and assessment of complete systems. The individual contributions come from industry, educational establishments and government research laboratories in the UK and the USA. The order of presentation in the book mainly follows the order in which the papers were presented at the seminar.
