<p>PURPOSE: To visually evaluate the existing extent of a target by displaying the positional error of the target derived from the target observation error, etc., of a target observing device together with the position of the target. CONSTITUTION: Of the flight path information of such a target as a traveling object, etc., estimated by a tracking device 2, the estimated position of the target is displayed 5. The positional error of the target derived from the target observing error, etc., of a target observing device 1 is also calculated 11 by using an error range threshold. A flight path information enlarging and displaying device is composed of a display which displays the track of the target and an enlarging and display 14 which displays the position of a target set by means of an enlarged target setter 12 and its surrounding area.</p> |
