TRACK INFORMATION INDICATOR

摘要

PROBLEM TO BE SOLVED: To visually assess the existing region of a target and predict/indicate future predicted position and prediction error range for the approaching target by indicating the target position error caused by the effects of target observation error, etc., in a target observation device. SOLUTION: This device consists of an indicator 7 which indicates target estimated position in target track information estimated about a target such as moving object with a tracking device 2, calculates also a target position error caused by the effects such as target observation error in a target observation device 1 by using an error range threshold and predicts and indicates the target future position and predicted error range at a time set with a prediction time setter 13 for a target perceived as an approaching target.
