<p>PROBLEM TO BE SOLVED: To obtain a target tracking device wherein information of the most likely hypothesis or the information showing the state of the whole group of hypotheses can be outputted at the arbitrary time point during processing. SOLUTION: An observation vector from a target observation device is inputted, a gate judgement matrix showing the whole possibility in which the whole observation vector corresponding to each cluster corresponding to an error signal, an already existing track and a new target respectively is calculated with a gate judgement matrix calculation part 5. A plurality of tracking correlation matrixes showing one expansion method of a hypothesis from the gate judgement matrix respectively is calculated with a tracking correlation matrix calculation part 7. A new hypothesis of high reality from the tracking correlation matrix and the already existing hypothesis is prepared by a hypothesis renewal part 9, the hypothesis is reduced by a hypothesis reduction part 19 at need, and information of the most likely hypothesis at the time or the information showing the state of the whole group of hypotheses is calculated to be outputted.</p> |
