Title: Target correlation apparatus
Inventor: HAYASHI MICHIKO
IPC: G01S13/72
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To eliminate a mismatching in correlation results by performing, on the basis of prioritized tracking-factor information and on the basis of a tracking-factor correlation result, the correlation processing operation of only a target as a correlation target extracted out of targets whose tracking factor has been calculated. SOLUTION: Target tracking devices 4 to 6 calculate tracking factors of respective targets on the basis of information or the like on a plurality of targets to be tracked, from target observation devices 1 to 3 and on the basis of a tracking factor in the past. Tracking factor databases 7 to 9 store information on the factors. A correlation- object-target extraction devices 10 to 12 correspond to the databases 7 to 9 to which the order of priority is given, and they extract correlation object targets on the basis of information from the databases and on the basis of a correlation result from a correlation result database 14. A tracking-factor correlation device 13 judges the combination of the correlation object targets.  When a database-controlled target T1 whose order of priority is 1 is correlated with a database-controlled target T2 whose order of priority is 2 and a database-controlled target T3 whose order of priority is 3, the targets T2, T3 are outside the correlation target of all targets. Thereby, a mismatching in the correlation results of the targets T2, T3 is not generated.
