KommPeilMA - Communication and Bearing Estimation based on Multimode Antennas


Unmanned aerial vehicles (UAVs) are one of the most important emerging fields in the area of aeronautics. A key factor is the save integration of UAVs into the 3D aviation space. Collisions need to be avoided by means of advanced technologies. This goal can only be solved by combining and improving different collision avoidance systems. Main focus of the Master360 project is the integration of UAVs in the non-segregated airspace. As an output, technological demonstrators are currently being developed which will perform information exchange between UAVs and recognition of airborne objects given lightweight equipment.

To miniaturize the equipment required for transponder-based direction-of-arrival and distance estimation, multimode antennas come into play. Multimode antennas provide several antenna ports on a single physical radiator, hence they are more compact compared to classical antenna array designs. A suitable antenna design will be developed by the project partner Leibniz University Hannover, and afterwards integrated into an interrogator concept. The interrogator unit will be provided by an industrial project partner. A main contribution of the chair of Information and Coding Theory is to design an optimized radiation pattern for the interrogator concept, as well as enabling sophisticated direction-of-arrival and position estimation algorithms. The calculated positions are provided to other project partners to successfully avoid collisions.
