LiDAR (Light Detection and Ranging) systems are emerging as critical elements for sensors in applications as diverse as autonomous vehicles to wind turbine management. Novel technology approaches are needed to create systems to deliver substantial improvements in performance, size, weight, power and cost, leading to new applications. Research and engineering of LIDAR systems can be very rewarding, due to its many facets, encompassing signal processing, lasers, optics, electronics, and modelling. This 4 year EngD project is to research the next generation of LIDAR systems. Starting from a survey of the state-of-the-art, the project will identify key areas of investigation, with particular emphasis in real areas of interest to Thales in markets such as defence, security, space and energy. The researcher will create system models to predict the performance and then design, build and test a real system in the lab and conduct field trials. The project will develop novel application of signal processing techniques, such as clutter Suppression, point cloud classification, tracking and georeferencing.
