Abstract: A receiver-system comprising a path-switching-unit, a redirect-switching-unit, a plurality of receive-paths, and a processor. The path-switching-unit has a plurality of path-switch-input-terminals that are each couplable to a receive-antenna. The redirect-switching-unit has a plurality of redirect-switch-output-terminals that are each associated with one of the plurality of path-switch-input-terminals in order to define a plurality of switch-terminal-pairs. The receive-paths are connected between a path-switch-output-terminal and a redirect-switch-input-terminal. The path-switching-unit and the redirect-switching-unit are configured to selectively connect each receive-path between different ones of the plurality of switch-terminal-pairs, based on a switch-control-signal. The processor can receive first-processor-input-signals from a first configuration of the plurality of receive paths selectively connected between the plurality of switch-terminal-pairs; receive further-processor-input-signals from one or more further configurations of the plurality of receive-paths selectively connected between the plurality of switch-terminal-pairs; and determine an angle-of-arrival associated with the input-signals based on the first-processor-input-signals and further-processor-input-signals.
