Abstract:
1. A radar device installed in a movable body and for transmitting electromagnetic waves at a predetermined frequency and receiving response waves transmitted from a transponder in response to the electromagnetic waves, respectively, the radar device comprising: a representative distance calculator configured to calculate a representative distance from the radar device to the transponder based on the response waves that are continuous over a predetermined azimuth angle range; a representative relative azimuth calculator configured to calculate a representative relative azimuth of the transponder from the radar device based on the continuous response waves; a positioning component configured to calculate a location of the radar device based on positional information of the transponder that is contained in each of the response waves, the calculated representative distance, and the calculated representative relative azimuth; and a removing component configured to remove, when only below a predetermined number of the continuous response waves over the predetermined azimuth angle range are received, the received response waves transmitted from the transponder.
