摘　　要：为研究自适应修正电子时间引信空炸与弹道炸的判定问题,根据引信定位模式的一般准则,通过分析2种发火模式的机理,以二项分布可靠度置信下限来确定随机散布的参数与弹道炸的距离上限;利用引信作用距离的概率分布特性,结合累积分布函数,计算引信空炸与弹道炸的边界值。在预定炸点为400m,空炸误差为±8m,空炸作用率为80%的情况下,计算得到的引信空炸与弹道炸的分界点约在371m处。研究方法为其他引信空炸与弹道炸的判定问题提供了理论基础,为军方与制造方对引信性能的检验提供了参考。To study the decision problem of air burst and ballistic burst in adaptive electronic time fuze,the ignition principle of air burst and ballistic burst was analyzed according to the general criterion of fuze positoning mode,and the random-diffusion parameter and the distance superiorlimit of ballistic burst was defined by confidence lower-limit of binomial distribution.Combined with the cumulative distribution function,the boundary values of air burst and ballistic burst were obtained on the basis of the probability characteristics of fuze effect range.For the predetermine bursting-point of 400 m,the air-burst error of±8 mand the acting rate of 80%,the demarcation point is about 371 m.This method provides a theoretical basis for the decision problem of air burst and ballistic burst in other fuze,and it also offers reference for testing the capability of fuze by the military and manufacturer.
