METHOD AND APPARATUS FOR CORRECTING INTERFEROMETER OF ARRAY ANTENNA WITH TILT ANGLE

摘要

The present invention relates to an interferometer correcting method and a device thereof which approximately compensate for deviations of a phase comparison and an amplitude comparison which occur in accordance with a tilt angle and/or an array environment of an array antenna so as to detect the direction of a signal source. According to the present invention, a deviation from a theoretical result can be compensated for wherein the theoretical result is generated due to a self-pattern feature and/or mutual interference of the array antenna having a tilt angle, and due to a scattering feature and the like of a material like a dielectric object and/or metal in surroundings, thereby reducing a direction detection deviation due to a structural shape.
