Apparatus and method for finding hybrid direction using two baselines

摘要

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.
