Abstract
An apparatus for measuring the relative direction of an incoming radio signal, the apparatus comprising at least first and second antennas, and comparison means for comparing the incoming radio signal as received at the first antenna with the incoming radio signal as received at the second antenna, and from the result of the comparison transmitting a measurement of the relative direction.

An apparatus for measuring the relative direction of an incoming radio signal, the apparatus comprising at least first and second antennas, and comparison means for comparing the incoming radio signal as received at the first antenna with the incoming radio signal as received at the second antenna, and from the result of the comparison transmitting a measurement of the relative direction, wherein the measurement of relative direction is used to modulate a version of the received radio signal which is then retransmitted.
