提高线圈靶测速精度的研究——波存测速研究报告之一

The Research of Inproving the Accuracy of Velocity Measurement with Coil Target——Report of the Research of Using Transient Digital Recorder to Measure the muzzle Velocity of Projectile

本文对电子测时仪——线圈靶测速系统进行了测速误差分析,指出触发误差是其主要误差,不能忽略.文章提出用波存代替测时仪与线圈靶组成新的系统测速,可以减小触发误差.

The article analyzes the errors of muzzle velocity measurement system of using chr-onometer and coil targets.It shows that trigger error is the main error of muzzle velocity mea-surement,so that it can not be neglected.It is also pointed out that by using a transient digitalrecorder to replace the chronometer,the error can be reduced greatly.
