| Abstract: | Various technologies pertaining to computing angle of arrival of radio
signals are described. A system that is configured for computing the
angle of arrival of a radio signal includes a cylindrical sheath wrapped
around a cylindrical object, where the cylindrical sheath acts as a
ground plane. The system further includes a plurality of antennas that
are positioned about an exterior surface of the cylindrical sheath, and
receivers respectively coupled to the antennas. The receivers output
measurements pertaining to the radio signal. A processing circuit
receives the measurements and computes the angle of arrival of the radio
signal based upon the measurements. |
