<p>PROBLEM TO BE SOLVED: To solve the problems called target transfer and lost that are caused when using a conventional window in target tracking for tracking a target on the basis of data related to a plurality of target positions obtained from sequentially obtained target signals.SOLUTION: A plurality of target positions obtained at a certain timing are correlated with a plurality of target positions to be matched being a plurality of target positions obtained at a past timing or a plurality of predicted target positions for a certain timing obtained on the basis of the target positions obtained at the past timing. Then, the target positions correlated with the target positions to be matched are stored in association with target identification data corresponding to the target positions to be matched, and as for the correlation, the plurality of target positions and the plurality of target positions to be matched are correlated such that a total sum of distances therebetween is minimized, and when a distance between a target position and a target position to be matched exceeds a prescribed distance which is modified according to target speed magnitude, correlation is not executed between the target position and the target position to be matched.</p> |
