Fractional Order Ship Tracking Correlation Algorithm

Aiming at the radar and AIS sensor's fuzzy association to ship tracking which caused by different error, this article provided fractional order ship tracking correlation model. From the mathematical point of view, the model used in this thesis extended the integer-order correlation measurement to the fractional-order correlation measurement; from the correlation of view, elongated the non-process correlation of the point information to the process correlation of the line information. Example shows that, fractional-order association algorithm can provide much more related information; and enhance the ship tracking correlative accuracy.
