Radar sensing has long been an indispensable tool for military surveillance and civil remote sensing. The ability to function day and night, in all weathers and to cover wide areas rapidly means that radar has found wide application from short ranges of a few hundred meters to space based operations. In recent years, radar systems have gone through something of a revolution with the advent of high speed, wide dynamic rage A to D converters and corresponding digital processors. This has led to array based antennas, ultra high range resolution and imaging, advanced adaptive processing for enhanced detection, tracking and target classification. Indeed, radar sensing is continually being extended and new areas such as cognitive sensing and sensing for autonomous applications are set to bring about a further revolution. This course begins by introducing the basic, underpinning concepts that are the foundation of all radar systems. It then builds on this to introduce contemporary methods for moving target detection, array antennas for radar, tracking, high-resolution techniques, imaging and target classification. Throughout the course, real life examples are used to illustrate the key points and ensure that concepts are presented in a realistic and meaningful way.
