Automotive Radar Demonstrator : Phase-locked loop and filterdesign

Abstract:   As technique and requirement of today’s products keeps expending, Acreo AB has been researching for automotive radar that fulfills these requirements, e.g. higher resolution, faster system and lower cost. The purpose of this master thesis work has been to evaluate a previous design and implement changes. The work has resulted in a PCB card that will be used to compare the performance between two radar modules. The demonstrator has been developed in two versions – first based on the existing GaAs-chipset (Gallium Arsenide) and a second with the inclusion of a low cost SiGe-chipset (Silicon Germanium). The outcome of this work proves that some requirements cannot be fulfilled and therefore a next-generation radar demonstrator has been proposed. The new radar demonstrator includes changes that can fulfill the requirements.
