Estimating Accuracy Parameters of Rapid-Fire Guns,

Abstract : To model an engagement involving rapid-fire guns implies the capability of supplying good estimates for the input parameters. Recent simulation studies by O.K. Bingham have exhibited enormous variability in the estimates calculated from samples of impact data. In this paper, the fundamental reasons for these large variances are brought out; new estimates (formulas) with moderate variances are derived; lower limits for the variances are established; and the important parameters, aiming error variance and the round-to-round correlation of the aiming error, are shown to be impossible to estimate.
