Shooting calculation device # (6) fires a bullet from a firearm.

Although the target position changes during the elapsed time until the bullet reaches the target, the target's ] > 1 (assuming that the moving direction and speed do not change, the future value IF is the point at which the target and the bullet meet. The delay device (16') is calculated as the future value 16' signal (7).
) and the future position error correction device t (241), and at the same time sends the bullet flight time signal Q51 to the delay device 6θe.In addition, the attack possibility status is calculated from the released future position and the effective range of the bullet, It is sent to the attack priority determination device as an attack possibility status signal (To).The future position correction device (2) adds the future position error signal 01 to the future position signal (7) in a manner that Calculate the corrected future position and send it to the hit rate 9 monk Q.

The hit rate is 1. The small device Hi (c) is obtained from the future position error correction device Qυ. The hit rate is calculated by dividing by the effective radius of the bullet depending on the insertion force ``4'' of the firearm (t81.

Although they almost overlap, for the sake of explanation they are separated by a distance that allows them to be distinguished.

In the explanation so far, the case where a target is tracked with a radar has been described, but the present invention is not limited to this, and may be used when a target is tracked optically or with a laser.

(Effects of the Invention) As described above, according to the present invention, even if the target changes its direction of movement, the future position signal can be easily corrected to the future position, and at the same time, the firearm selection control device can easily correct the future position signal.
