Title:
RADAR AXIS DEVIATION CORRECTION SYSTEM AND RADAR AXIS DEVIATION CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/102231
Kind Code:
A1
Abstract:
Provided is a radar axis deviation correction system that makes it possible to detect and correct the axial deviation of two radars with high sensitivity. This radar axis deviation correction system is characterized by comprising a first radar that detects first object information, a second radar that detects second object information, and an electronic control unit that individually detects and corrects the axial deviation of the first radar and second radar on the basis of the first object information and second object information, and in that if there is a specific target in the range where the field of view regions of the first radar and second radar overlap and two items of distance information or angle information that relate to the specific target and are included in the first object information and second object information meet a predetermined condition, the electronic control unit determines whether a position of the specific target based on information that is not the two items of information and is included in first object information and second object information detected at the same time falls within a predetermined error range, and if the position of the specific target does not fall within the error range, corrects the axial deviation of the first radar or second radar.
