Title:
POSITION INFORMATION DERIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/013462
Kind Code:
A1
Abstract:
A position information deriving system (100) is provided with: an antenna device (1) which includes an azimuth angle antenna (11) and an elevation angle antenna (12), and which emits radio waves onto a detection target and receives reflected waves from the detection target; an azimuth angle information acquiring unit (16) for acquiring a distance to the detection target and an azimuth angle of the detection target on the basis of the reflected waves detected by the azimuth angle antenna; an elevation angle information acquiring unit (17) for acquiring a distance to the detection target and an angle of elevation of the detection target on the basis of the reflected waves detected by the elevation angle antenna; a determining unit (18) which performs a distance comparison between the distance obtained by the azimuth angle information acquiring unit and the distance obtained by the elevation angle information acquiring unit, and which determines that detection targets having identical values are an identical detected object; and a deriving unit (19) which derives position related information related to the position of the identical detected object from the azimuth angle, the angle of elevation, and the distance of the identical detected object.
