For the problem of the multi-target fuzzy association, the fractional is introduced to tracking correlation, and
the multi-target fractional order tracking correlation model is proposed. From the mathematical point of view, the integer-
order correlation measurement is extended to the fractional-order correlation measurement. From the correlation of view,
the non-process correlation of the point information is elongated to the process correlation of the line information. Example
shows that, the fractional-order association algorithm can provide much more related information, and enhance the tracking
correlative accuracy.
