Salvo Hit Probabilities for Offset Circular Targets

Abstract

A method, with necessary graphs, is furnished for estimating the probability of at least one hit per salvo round of n missiles for different values of standard deviation for aiming errors of the rounds and ballistic errors or dispersions of the n missiles about their center of impact for the round. The method permits the solution of the problem when the center of impact of the missiles is offset from the center of the target, by expressing the missiles distribution in terms of the distance from the center of the target instead of from the center of impact. Also presented, as of related interest, are approximations of the single-missile round-hit probability for offset circular targets.
