IMPROVED THEORY OF GENERALIZED METEO-BALLISTIC WEIGHTING FACTOR FUNCTIONS AND THEIR USE

摘要

It follows from the analysis of artillery fire errors that approximately two-thirds of theinaccuracy of indirect artillery fire is caused by inaccuracies in the determination of themeteo parameters included in fire error budget model.Trajectories calculated under non-standard conditions are considered to be perturbed. Thetools utilized for the analysis of perturbed trajectories are weighting factor functions (WFFs)which are a special kind of sensitivity functions. WFFs are used for calculation of meteoballistic elements μB (ballistic wind wB, density ρB, virtual temperature τB, pressure pB) aswell.We have found that the existing theory of WFFs calculation has several significantshortcomings.The aim of the article is to present a new, improved theory of generalized WFFs thateliminates the deficiencies found. Using this theory will improve methods for designingfiring tables, fire control systems algorithms, and meteo message generation algorithms.
