Abstract
An apparatus, method, or computer-readable storage medium encoded with computer-executable instructions that, when executed by a computer, cause the computer to carry out a method for determining one or more directions of arrival of one or more coherent or incoherent signals with a single radio frequency channel. The apparatus may comprise: a plurality of antenna elements (110) configured to determine the one or more coherent or incoherent signals; a plurality of radio frequency switches (120) configured to selectively activate one or more of the plurality of antenna elements; and a radio frequency combiner (140) configured to combine a plurality of radio frequency signals from one or more selectively activated antenna elements of the plurality of antenna elements.
