Abstract: In order to guide the later application of the image terminal guidance shell, the shooting efficiency is analyzed. The exterior trajectory of image terminal guidance shell is divided into non-control section, middle guidance section and terminal guidance section. The error, effective area and hit probability of each stage are analyzed, and the shot hit probability and damage probability of fixed and moving targets are calculated under different conditions. Compare it with ordinary grenade and laser terminal guidance shell. The results show that the shooting efficiency and distance of the image terminal guided projectile are not related, which is higher than that of the laser terminal guided projectile, and the hit probability of the armored point target is above 0.7. This study can provide theoretical support for the specific operational application of the projectile in the next stage.
