摘　　要：分析了大中心距、多管自动火炮立靶密集度试验有少量脱靶弹存在时,不剔除脱靶弹数据的立靶密集度试验数据处理方法.在有脱靶弹时单管火炮立靶密集度估计理论的基础上,通过引入方位系数和径向综合系数,推导出大中心距、多管自动火炮综合散布方差与各管散布方差的关系以及相关计算公式,得出了大中心距、多管自动火炮在不剔除少量脱靶弹数据情况下的立靶密集度计算及其误差估计公式.实例计算表明该方法计算精度较高,能够解决大中心距、多管自动火炮研究和交验试验中有脱靶弹存在情况下的密集度估计问题.The test data processing method was researched while there are a few of missing projectiles in the vertical target dispersion tests of large axial distance multi-barrel automatic gun, Based on vertical target density of test data estimating theory of single barrel automatic gun, the relationship of large axial distance multi-barrel automatic gun＇s total variance and individual variances of each barrel was studied by introducing azimuth coefficients and synthesized radial coefficients. The computational equations of vertical target density of pattern and its error estimating formula of the gun were obtained without picking out the test data of a few of missing projectiles. The example indicates that the presision of the method is high, and it can be used to estimate the vertical target dispersion in research and production acceptance test of large axial distance multi-barrel automatic gun.
