弹丸初速激光测定系统研究

Research on Projectile Muzzle Velocity Measurement System Based on Laser

本文对多普勒雷达测速、天幕靶测速和激光测速的原理进行了对比分析,详述了以89C52单片机为核心的新型激光初速测定仪原理、电路设计和火炮初速推算方法.同时,围绕影响测试精度的因素进行了分析探讨,确定了测定各种火炮初速所需的靶距和第一靶距炮口的最小距离.

By analyzing the velocimetry principle of doppler radar,sky screen and laser.A theory of new laser velocimetry system based on single chip microcontroller 89C52,circle design and the calcula-tion method of muzzle velocity was put forward detailedly.According to the factors of affecting the test’ s accuracy,we developed a variety of target distance of measuring artilleries’muzzle velocity and the minimum distance from the first target to muzzle.
