Venue: Menzies Seminar Room, 6th Floor, Menzies Building (Upper Campus), University of Cape Town
The principal aim of this course is to introduce students to the fundamental principles underlying radar systems and to enable them to understand and apply these principles to generic radar systems. The subject is specifically structured around these aims. On successful completion of this course, students will be able to:
describe the main principles underlying radar systems.
understand the role of each component of a radar system.
use the radar equation to describe the performance of radar systems.
understand how target and environmental characteristics affect the choice of system design parameters.
describe and assess the relative advantages of different types of radars.

Prof Douglas A. Gray is the Professor of Electrical Engineering at the Adelaide University and Director of the University of Adelaide Radar Research Centre.
He received his Ph. D. from the University of Adelaide, in 1973 and then spent 20 years with the Defence Science and Technology Organisation, applying signal processing to sonar and electronic warfare and leading various research and development programs.
From 1993 to 2006, he was Deputy Director of the Cooperative Research Centre for Sensor Signal and Information Processing and led a number of programs and projects in radar, sonar and GPS.
His current radar research interests are in MIMO radar, radar for monitoring weather and bushfires and synthetic aperture radar for surveillance and environmental monitoring.
