摘　　要：为检验航炮服役期内射击密集度是否满足规定要求,结合热校靶工作,根据弹着点在靶板上的坐标值的平方和构造射击密集度检验统计量,针对平时和战时不同的情况分别设置控制弃真和存伪错误概率的假设检验方案:平时热校靶检验射击密集度,以控制弃真错误概率为显著性水平;战时以控制存伪错误概率为显著性水平。仿真结果表明:检验射击密集度过程中,控制弃真错误概率时,存伪错误概率为射击散布标准差的减函数;控制存伪错误概率时,弃真错误概率为射击散布标准差的增函数;在其他条件不变的情况下,降低某一种错误概率,会导致另一种错误概率的增大。研究结果可为航炮射击密集度检验提供一定的理论依据,为监控航炮健康状况提供客观依据。To test whether an in-service aircraft gun′s firing dispersion met designed requirements,statistics were tested by constructed firing dispersion and the sums of squared coordinate values which were collected from the target board during live-fire calibration.Two kinds of hypothetical testing plans controlling type I and type II errors were provided for peace time and war time.During peace time live-fire calibration,type I error was considered as significance level.During war time,type II error was considered as significance level.Simulation results indicate that type II error probability was the decreasing function of firing dispersion standard deviation when type I error probability was restricted.Type I error probability was the increasing function of firing dispersion standard deviation when type II error probability was restricted.With other conditions remaining unchanged,the reduction of any type of error probability would lead to the increase of the other type error probability.The research results can serve as the theoretical basis for the firing dispersion test of aircraft guns,and provide the objective basis for monitoring the health level of aircraft guns.
