TARGET MOTION PREDICTION APPARATUS AND TARGET MOTION PREDICTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a target motion prediction apparatus capable of changing smooth performance or follow-up performance of a motion predicting filter and predicting motion of a target by accurately determining veering/gear shift using Doppler speed.SOLUTION: A predicted Doppler speed of a target when uniform linear motion of the target is supposed is found out and a Doppler speed variation to be a difference between the predicted Doppler speed of the target and a detected Doppler speed is found out. Further a veering/gear shift level expressing possibility of performance of veering/gear shift in accordance with magnitude of the Doppler speed variation is found out and the motion predicting filter of the target is changed to change followability or smoothness of the filter.
