<p>PURPOSE:To prevent wrong discrimination to contrive the reliability improvement of a discriminating result of same track by adding a same track discriminator of one to one and discriminating whether one track of a track maker and a plurality of tracks of another track maker are same target each other. CONSTITUTION:In a track data selector 15 respective track data from track data of data-stored 14 track makers 9, 12 are selected to calculate the difference of their tracks with the use of a track difference calculator 16 so as to calculate 17 error covariance matrix which is the error assessment of the difference. Next, testing is performed on whether the track between the makers 9, 12 is a datum from the same data with the use of a same track reference device 18 and the matrix of the same track check result in regard to the whole pair of the tracks is stored 19. And the matrix display of the same track discrimination hypothesis corresponding to one to one on the basis of the matrix display of the same track check result is calculated with the use of a hypothesis generation device 20 and after a degree of reliability corresponding to each hypothesis is calculated 21, the same track discrimination 22 corresponding to one to one is performed. Thereby the reliability of the discrimination result of the track data from the same target can be improved.</p> |
