1. A tracking apparatus for tracking an object by the use of a plurality of detecting data sets which are successively supplied from a detecting device and finding a presumed position and a presumed velocity of said object at the latest detecting time of said detecting data sets, said tracking apparatus comprising;

  • regression curve calculating portion for finding two regression functions individually corresponding to time variation of X and Y coordinates of said object on a predetermined X-Y coordinate system by the use of said detected data sets, position presuming portion connected to said regression curve calculating portion for finding said presumed position by the use of said regression functions and the latest detecting time, and velocity presuming portion connected to said regression curve calculating portion for finding said presumed velocity by the use of said regression functions and at least one of the other detecting times of said detected data sets.
