PROBLEM TO BE SOLVED: To provide a radar reference azimuth correction device for precisely correcting a reference azimuth that is reference for a radar apparatus in a detecting direction.;SOLUTION: A radar reference azimuth correction device includes a relative position obtainment part, an absolute position obtainment part, an operation part, and a correction part. The relative position obtainment part obtains a relative position of a target relative to a radar apparatus (radar antenna). The absolute position obtainment part obtains an absolute position of the radar apparatus and that of the target. The operation part calculates an error angle that is the difference between a direction of the target relative to the radar apparatus on the basis of the relative position and a direction of the target relative to the radar apparatus on the basis of the absolute position. The correction part corrects the reference azimuth on the basis of the error angle calculated by the operation part.;COPYRIGHT: (C)2013,JPO&INPIT
