Abstract
Provided is a radar system which calculates a track of a detected object and can determine whether or not the track is accurate. The radar system includes: a radar section for emitting an electromagnetic wave to an object and receiving a reflected wave reflected from the object to detect position information of the object; a track calculation section for calculating, periodically at a first cycle, a track along which the object moves, on the basis of the position information obtained from the radar section; a first speed calculation section for calculating a first speed at which the object moves, on the basis of pieces of the position information at two different time points having a time interval which is longer than the first cycle; and a track determination section for determining whether or not the track is accurate, on the basis of at least the first speed.
