PURPOSE: To provide a multiple guidance device of an airframe which is capable of discriminating whether it is a target or a non target by finding the direction and the size of the target and guiding a larger target preferentially when there exist a plurality of targets.

CONSTITUTION: A multiple guidance device of an airframe is provided with an active raider 3 ad an image sensor 5 and a computer 4 where the computer 4 inputs a distance RL from an airframe 2 up to the left end of a target 1 and a distance RR from the airframe 2 up to the right end of the target 1 by means of the active raider 3 and inputs a visible image angle θ from the image sensor 5 to the target and computes the size L of the target 1 and its direction and outputs a control signal to a control device of the airframe 2.
