Rotating antenna system and method for bearing and / or position determination

Abstract

A rotating antenna system (10) is provided for direction finding and / or positioning with respect to a signal source (11) that wirelessly transmits a radio frequency (RF) signal. The rotating antenna system (10) comprises at least two antennas (12a, 12b), with at least two receiving units (13a, 13b) each connected to a corresponding antenna (12a, 12b), a rotating positioning unit (14) configured to rotate at least one or at least two or each of the antennas (12a, 12b) about a pivot point and / or axis of rotation (15), and a processing unit (16) connected to the antennas (12a, 13b). Each of the at least two receiving units (13a, 13b) is configured to receive, with the help of the at least two antennas (12a, 12b), a corresponding one of at least two reception results with respect to the RF signal during rotation.The processing unit (16) is configured to determine a corresponding direction and / or estimate a corresponding position in relation to the signal source (11) based on at least one or at least two or each of the at least two received results.
