<p>PROBLEM TO BE SOLVED: To obtain a target tracking device wherein the state of an important hypothesis or the state in which the whole hypothesis is arranged is shown and state judgement of a user can be helped. SOLUTION: An observation vector from a target observation device 17 is inputted, a gate judgement matrix showing the whole possibility in which the whole observation vector corresponding to each cluster corresponds to an error signal, an already existing track and a new target is calculated with a calculation part 5. A plurality of tracking correlation matrixes showing one expansion method of hypotheses from the gate judgement matrix respectively is calculated with a calculation part 7, and a new hypothesis of high reality from the tracking correlation matrix and the already existing hypothesis is prepared with a hypothesis renewal part 9. The hypothesis is reduced with a hypothesis reduction part 19 at need, the most important hypothesis is selected with a tracking determination part 15 or the whole information is arranged and extracted, and the state of the most important hypothesis or the whole information is multilaterally shown on a target display 18a.</p> |
