舰炮测速雷达的初速预测精度分析

Analysis on Velocity Prediction Precision for Muzzle Velocity Radar of A Type of Gun

测速雷达有效提高了火炮系统射击精度,而对于初速的预测模型各型火炮还不尽相同。针对火炮连续效力射下的初速随机散布,采用当前射击滑动平均初速作为预测值以及当前射击前的全部初速平均值作为预测值,求得预测值与当前实际测量值的一次差,并对结果进行统计分析,观察各种统计样本下的初速预测精度。

The muzzle velocity radar enhances gun firing precision effectively,but velocity prediction models of different guns are not the same.Aimed at the velocity random dispersion of the continuous firing of a type of gun,by means of regarding average velocity of the finite number of projectiles that were adjacent before current firing and all average velocity before current firing as prediction,the difference between prediction and current measured value is acquired,and velocity prediction precision of different sample number are acquired by statistic analysis that aimed at the result.
