Abstract: Disclosed is a hybrid direction detection apparatus and method that may perform a precise direction detection through a one-time rotation of a log period (LP) antenna and a one-time phase difference measurement of a dipole antenna and may remove an ambiguity error of the LP antenna by two dipole antennas spaced apart by a distance of about 0.5λ by finding an approximate direction using the LP antenna that is a directional antenna, by measuring a phase difference between arrival waves using two baselines including two dipole antenna in the corresponding direction, and thereby precisely finding a final direction.

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.
