PURPOSE:To attain to enhance correlation accuracy, by performing correlation with due regard to the timewise transition of a target. CONSTITUTION:When data due to initial information from a specific observation system is inputted, the presence of absence of interrelation is judged but judgement of sameness is not directly performed even if target having correlation with the initial information is present and an initial value I0 is set to a counter I while final judgement is reserved (1). On the other hand, target data having correlation is absent (2), judgement of a different target is directly drawn and a lower limit value IMIN is set to a counter. When the presence of correlation target data is judged by the initial information, the judgement of correlation is repeated every when there is altered data and, if correlation is present, count-up is performed as shown by (3), (4), (5) and, if there is not correlation, count-down is performed as shown by (6)...(9). By this method, when a final count value reaches an upper limit value IMAX, the judgement of a same target is drawn and subsequent judgement is not performed. When the count value reaches a lower limit value IMIN, the judgement of a separate target is drawn and no subsequent judgement is performed. Therefore, when the content of the counter reaches IMAX or IMIN, judgement of the same target or not is decided. |
