The Probability of Hit of the Antiarmor Cluster Munition

摘要

One weapon system concept proposed as a Wide-Area Antiarmor Munition (WAAM) is the Antiarmor Cluster Munition (ACM). The ACM consists of a clustered bomb unit (CBU) dropped to the battlefield by parachute; during its descent the system behaves like a damped spherical pendulum. At a certain preprogrammed height (nominally 1m) the CBU detonates, sending forth discrete warheads at hypervelocities. This method of delivery gives rise to certain ramifications regarding the probability that a warhead will hit a target. Specifically, the pendular motion acts to degrade the probability of hit pH. This paper presents a formal derivation of pH with regard to hitting a solitary target; the treatment entails coupling the physics of the pendulum to geometrical considerations. It also presents numerical examples which show pH is quite sensitive to the (ensemble-averaged) maximum amplitude of the pendular motion. (Author)
