<p>PROBLEM TO BE SOLVED: To make it possible to evaluate the range of the presence of a target visually by displaying even the target-position error generated by the effect of the target-position error or the like in a target observing device and to estimate/display the future predicted position of an approaching target. SOLUTION: For the target such as a moving body, the estimated target position among the target track information estimated in a tracking device 2 is displayed. At the same time, even the target-position error generated by the effect of the target observation error or the like in a target observing device 1 is computed by using the threshold value of the error range. Furthermore, the further target position at the time set by an estimating-time setting device 13 is estimated for the target, which is confirmed as the approaching target, and displayed on a display device 7. Furthermore, the target, which is set by an expanded-target setting device 82, is displayed on an expanded display device 83.</p> |
