【主讲人简介】

Hugh Griffiths holds the THALES/Royal Academy Chair of RF Sensors in the Department of Electronic and Electrical Engineering at University College London, England, and is Chair of the Defence Science Expert Committee (DSEC) in the UK Ministry of Defence.  From 2006–2008 he served as Principal of the Defence Academy College of Management and Technology. He received the MA degree in Physics from Oxford University in 1975, then spent three years working in industry, before joining University College London, where he received the PhD degree in 1986 and the DSc(Eng) degree in 2000, and served as Head of Department from 2001–2006.

His research interests include radar systems and signal processing (particularly bistatic radar and synthetic aperture radar), and antenna measurement techniques.  He serves as Editor-in-Chief of the IET Radar, Sonar and Navigation journal. He has published over five hundred papers and technical articles in the fields of radar, antennas and sonar.  He has received several awards and prizes, including the IEEE Picard Medal (2017), IET Achievement Medal (2017), the IEEE AES Mimno Award (2015), the IET A.F. Harvey Prize (2012) and the IEEE AES Nathanson Award (1996). He is a Fellow of the IET (previously IEE), Fellow of the IEEE, and in 1997 he was elected to Fellowship of the Royal Academy of Engineering.

【讲座摘要】

This is a one-day introductory course covering all key aspects of airborne radar systems. Stimson’s book has been used over many years as the go to introductory text for students, engineers and technicians alike. This tutorial course is to be given by Professor Hugh Griffiths, the lead author of the latest and substantially revised 3rd edition. It takes the form of a “taster” course, concentrating on the key underlying concepts that form the fundamentals of modern airborne radar system design. Whether attendees are new to radar or in need of a refresher of the basics, this course will help grasp the terminology, concepts, design-trades and applications of modern radar systems. The course closely follows the third edition of the book, providing an enduring reference for attendees.

Suggested pre-requisites:
There are no strict pre-requisites for this lecture. A basic understanding of signals and systems, DSP and elementary statistics to second year university level is assumed.
