PROBLEM TO BE SOLVED: To provide a target correlation device constituted so as to reduce the computer load in correlation processing by successively extracting target tracking specification data with higher priority from target tracking specification data as a target of priority correlation object and determining whether the extracted target specification tracking data are obtained from the same target or not in correlation decision processing in which all targets can be carried out only at the same time in a conventional target correlation device. SOLUTION: Priority is given to a tracking target according to error co- dispersion value by use of a correlation object priority giving device by first and second error co-dispersion values, so that the correlation decision processing of the target can be performed in the order of priority by use of a first correction object extracting device. Accordingly, the possibility with no binunique correlation can be reduced to reduce the computer load in the correlation processing.
