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.
Claims18
An apparatus for determining one or more directions of arrival of one or more coherent or incoherent signals with a single radio frequency channel, the apparatus comprising:
- a plurality of antenna elements configured to determine the one or more coherent or incoherent signals;
- a plurality of radio frequency switches configured to selectively activate one or more of the plurality of antenna elements based on a pre-determined pseudo-random switching pattern;
- and
- a radio frequency combiner configured to combine a plurality of radio frequency signals from one or more selectively activated antenna elements of the plurality of antenna elements.
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 method comprising:
- sensing, using a plurality of antenna elements, the one or more coherent or incoherent signals;
- selectively activating, using a plurality of radio frequency switches, one or more of the plurality of antenna elements based on a pre-determined pseudo-random switching pattern;
- and
- combining, using a radio frequency combiner, a plurality of radio frequency signals from one or more selectively activated antenna elements of the plurality of antenna elements.
At least one non-transitory 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 method comprising:
- sensing, using a plurality of antenna elements, the one or more coherent or incoherent signals;
- selectively activating, using a plurality of radio frequency switches, one or more of the plurality of antenna elements based on a pre-determined pseudo-random switching pattern;
- and
- combining, using a radio frequency combiner, a plurality of radio frequency signals from one or more selectively activated antenna elements of the plurality of antenna elements.
