摘要
简述了利用常规天幕靶测量弹丸运动速度的方法及在用于双头弹、连发弹速度测量中存在的问题,提出了一种在现有天幕靶基础上进行改进设计的方法,用信号采集卡代替天幕靶中的电子计时仪,并编写相应的信号处理软件,直接对天幕靶采集到的弹丸过靶信号进行分析处理,提取出信号的时间间隔。实验结果表明该方法可以准确测量出双头弹、连发弹的弹丸初速度。
The traditional methods of measuring projectile＇s velocity with sky screen and the problems confronted within measuring motion of duplex ammunition and repeated firing ammunition are described briefly. A method based on traditional sky screen is improved and studied, which using signal acquisition card to collect the signals of projectile and using software to process the signals. The results proved the validity of this method.
