Abstract: A hybrid direction apparatus and method that rapidly and accurately detects a direction of a radio signal source based on a direction detecting scheme by comparing an amplitude or signal strength, a virtual Doppler scheme, a phase difference comparison scheme while removing an ambiguity based on an amplitude or signal strength scheme, and identify a direction relatively precisely based on a phase difference scheme using only two antennas. Also, an arrival direction of a relative radio wave when an arrival direction of a radio wave is vertical to a single rotating axis may be precisely identified by mounting a directional antenna and a phase comparison antenna on the single rotating axis, and rotating the two antennas.
