1. An RF power detector comprising:
first and second antennas each adapted to receive an RF signal and each having a dimension defined by a wavelength of the RF signal;
a narrow-band RF power converter adapted to convert the RF signal to a DC signal;
a processor;
a position sensor coupled to the processor and adapted to supply position information to the processor, wherein the processor is adapted to identify a position of the source of the RF signal in accordance with the position information supplied by the position sensor; and
an orientation sensor coupled to the processor and adapted to supply orientation information to the processor, wherein the processor is adapted to identify an orientation of the source of the RF signal in accordance with the orientation information supplied by the orientation sensor.
