On RSSI-based direction-of-arrival estimation using multibeam antennas
Mario Schühler, Lars Weisgerber, Burak Sahinbas · 2017
An approach for direction-of-arrival estimation is presented that relies on a multibeam antenna. The antenna provides a pre-defined set of radiation patterns with distinct main directions. The approach considers only magnitudes of a received signal after its decomposition by means of a beam-forming network. Its application to measured signals obtained from an experimental setup is discussed, revealing that the resolution of the direction estimated is not limited by the beamwidth of the radiation patterns.
