<P>PROBLEM TO BE SOLVED: To obtain a tracker for predicting an unguided target track with high accuracy after finishing observation in a situation where a motion model does not coincide with actual motion by using a result of observing and tracking the motion model by a radar sensor. <P>SOLUTION: An initial condition estimation part 2 estimates an initial condition of an unguided target on the basis of a difference between an observation value acquired by a target observation device 101 and a smoothing value calculated by tracking processing of a track processing part 1 by using the observation value, and the known standard initial condition. A model correction amount calculation part 3 calculates a correction amount for the motion model on the basis of the initial condition, and a track prediction part 4 predicts the unguided target track after finishing the observation by correcting the motion model used by the track processing part 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
