PROBLEM TO BE SOLVED: To obtain a tracking device that highly accurately predicts a future position of a non-guided object after completion of observation without increasing a processing load even in a case where a period of time when the object can be observed by a radar sensor is short.SOLUTION: A tracking device comprises: an orbit correction amount estimation section 700 for generating an orbit correction amount estimation value with respect to a standard orbit by using tracking processing in consideration of a differential equation on the basis of a difference between the standard orbit calculated on the basis of the differential equation assuming known standard conditions in association with a non-guided target of which a position and a speed at certain timing are known and an observation value obtained by a radar sensor; and an orbit prediction section 800 that generates an orbit correction amount prediction value after completion of observation by the radar sensor in consideration of the differential equation on the basis of the correction amount estimation value generated by the orbit correction amount estimation section 700, corrects the standard orbit by adding the orbit correction amount prediction value to the standard orbit and predicts the future position and the speed of the non-guided target after the completion of the observation by the radar sensor. |
