Digital Control of a VCO for Radar Applications

Abstract: Radar systems have been around since the early 20th century, and technology is advancing at an ever-increasing speed. This has led to great achievements in radar development, which have expanded the technology's area of use. One of these is the application of a security radar used in conjunction with security cameras for increased flexibility and reliability in security systems. A type of radar that is suited for security applications is the frequency modulated continuous wave radar, and it requires a control system to stay within the allocated radar frequency spectrum and to increase the radar's performance. This control system is often implemented with analogue components, which comes with extra costs and space requirements. This master thesis aims to investigate a digital control method and analyse the performance of it. This comes with the advantage of not requiring any extra components for the control system and rely on the micro control unit used to analyse the radar data.
