Projects:2021s1-13010 Socially Distant Radar

Introduction

Radars use radio waves with the principle of echolocation to estimate the location and velocity of targets. A radar system consists of a transmitter producing radio waves, a receiver to collect any scattered waves and a series of processing steps to obtain useful information about any target(s) present. In recent times, passive radars have gained prominence as they use `transmitters of opportunity’, which greatly lowers cost and detectability. A modern radar system often uses a phased array antenna, capable of generating a number of beams to improve the ability to resolve targets with different directions of arrival. For this to work, the multiple channels need to be coherent or phase locked, which present a great technical challenge. An alternative is to use a multi-static system – one with multiple pairs of transmitters and receivers – to provide angle resolution. This project uses a number of 2-channel passive radar systems to detect targets on an ellipsoid and computes the intersections of these ellipsoids to resolve the target in angle. This project will develop skills and knowledge in a key technology of interest to defence. Many of the hardware and software know-how are easily transferable to other fields such as communications and RF engineering. It offers an opportunity to work with scientists and engineers in the defence sector, exposing you to professional practice in a major growth industry in South Australia.
