this thesis present the systematic studies on firing accuracy and firing accuracy tactical & technical requirement reasoning for gunnery system . the main contents of the paper are as follows . ( 1 ) definitions and probability distribution expressions for error of fire, error of firing data and error of dispersion are given summarily . methods to compose error of initial firing data and error of dispersion are discussed 本文對(duì)遠(yuǎn)程炮武器系統(tǒng)射擊精度及射擊精度戰(zhàn)術(shù)技術(shù)指標(biāo)論證等方面問(wèn)題進(jìn)行了深入、系統(tǒng)的分析研究,本文研究工作的主要內(nèi)容有:(1)概要地討論了射擊誤差、諸元誤差、散布誤差的定義及其概率分布,諸元誤差、散布誤差及射擊誤差的合成,分析了射擊精度的各種表示法,闡述了火炮武器系統(tǒng)準(zhǔn)確度、密集度和首發(fā)命中概率的估算方法。
