Abstract

Abstract: After the one-dimensional trajectory correction projectile out of the muzzle, various disturbance factors caused the impact point dispersion. Monte Carlo method was utilized on the shooting accuracy analysis. Based on the practical test datasets, three major factors were determined, namely, time delay of opening-damper mechanism, error of drag coefficient and measurement error of target. As to the disturbances, function randn was used for the analysis of the three major factors on the flat of Matlab. According to error distribution of the factors, the probability distribution and dispersion of the impact point were obtained. The maximum and minimum ranges of allowable errors were determined. Simulation results show that, the minimum range of the errors can meet the requirement of the shooting accuracy, which provides some basis for further improvement of correction accuracy.
