Abstract:

When using hovering deep bombs to intercept incoming torpedoes, multiple deep bombs are deployed along the possible torpedo path to form an interceptor line, thus increasing the probability of damaging the torpedo. The traditional deployment method is based on the detection error of the torpedo and the radius of destruction of the deep shells. It determines the probable passage interval of the target and distributes the deep shells evenly. However, the traditional method does not take into account the firing error of the deep ammunition or allow for a reasonable number of deep ammunition deployments and aiming points based on a predetermined damage probability. To address this, an optimal interception model is constructed by taking the destruction probability as the predetermined index, considering both observation error and firing error. By constructing an intermediate function, the theoretical optimal damage probability is obtained, and the predetermined damage probability is used as input for iteratively solving the number of deep bombs to be deployed based on the optimal damage probability. Finally, the targeting point of deep bomb deployment is determined by analyzing the interception strategy. Simulation calculations show that this method can quickly obtain the optimal number of projectiles and aiming points based on the predetermined firing probability. The error between the verified damage probability and the predetermined damage probability of the scheme is less than 1%, achieving the accurate deployment of the underwater interception line.
