Abstract
PURPOSE: To enable the indirect measurement of a target without projecting electromagnetic waves on the target by calculating a target distance from the altitude signal outputted by an altitude detecting part and the target depression and elevation angle signal outputted by a target depression and elevation angle calculating part.
CONSTITUTION: The field bearing of an image pickup device 1 is controlled toward the target by the field bearing reference tracking angle signal obtd. by tracking 2 the assigned target image in the signal image inputted from the image pickup part 1 and the control signal to be manually inputted. The field bearing angle of the image pickup part 1 is then detected 4. The depression and elevation angle of the target is calculated 6 from said field bearing angle signal and the field bearing reference tracking angle signal. The altitude of the observation point is then detected in the altitude detecting part 7. The distance of the target is calculated 8 from the depression and elevation angle signal of the target and the altitude signal of the observation point. An image display part 5 displays the picked up image to which the target is assigned and the distance of the target.
