Abstract

This thesis investigates some of the challenges involved in developing technology for a hypothetical lightweight multifunction radar system incorporating element level digitisation. The benefits of a digital array are well understood, but development of the technologies involved has been slow. Market drivers for this type of system are reviewed from the perspective of SELEX Galileo and the state of the art for existing and emerging technologies are explored. There follows an investigation of potential architectures for an element-level receiver in which the merits of different approaches are compared, leading to a recommendation for the most appropriate architecture for a commercial system. Alternative implementations of this receiver are discussed and compared, including making use of consumer technology as an alternative to custom microwave integrated circuits. This concludes with a proposal for the further work required to produce a prototype receiver. Finally, a novel filter aimed at solving a specific problem in existing radar architectures is developed and its performance demonstrated through simulation. Throughout the work, close attention is paid to key technology barriers that limit further advancement in the matters considered.
