RADAR DEVICE, RADAR POSITIONING SYSTEM, RADAR POSITIONING METHOD, AND COMPUTER READABLE MEDIA STORING RADAR POSITIONING PROGRAM

摘要

A radar device is provided. The radar device is installed in a movable body, transmits electromagnetic waves at a predetermined frequency, and receives response waves transmitted from a transponder device in response to the electromagnetic waves, respectively. The radar device includes a representative distance calculating module for calculating a representative distance from the radar device to the transponder device based on the response waves that are continuous over a predetermined azimuth angle range, a representative relative azimuth calculating module for calculating a representative relative azimuth of the transponder device from the radar device based on the continuous response waves, and a positioning module for calculating a location of the radar device based on positional information of the transponder device that is contained in each of the response waves, the calculated representative distance, and the calculated representative relative azimuth.
