Abstract
A projectile based targeting system for underwater objects includes a trainable gun terminal mounted in a waterproof housing. The gun terminal includes plural gun barrels terminating in waterproof breeches. Noise generating projectiles are launched from the gun barrels, and a fire control system selectively fires the projectiles from each of the plural gun barrels in a noise pattern. A host controller detects and processes noise generated by a launched pattern of the noise generating projectiles to give information about the objects. The projectiles each include a void region connected to an outer surface of the projectile by a hole formed in a neck of the projectile. Launching of the projectile creates a vaporous cavity around the projectile and thus the hole, thereby causing the void region to resonate at a noise generating frequency.
