Description
Summary:This paper presents a new development of a 24 GHz radar frontend with a Rotman Lens as a beamforming network. The main objective of the project is the accurate detection and localization of multiple targets at the same distance from the radar system. Interferometric systems determine the direction for a target with the phase difference through at least two receiving antennas. If multiple targets are located on the same distance but another angle or via multipath dispersion, the measurements can't discriminate between these targets. The proposed system can be used for different applications, e.g. collision avoidance or monitoring of critical areas.
