ACCURACY ANALYSIS FOR THE MEASURING SYSTEM OF TARGET DEVIATION FOR PROJECTILES SHOOTING AN ACOUSTIC TARGET

本文根据空气动力学理论 ,阐述了超音速弹丸的激波特性和利用该特性来测量弹目偏差的原理。分析了影响弹目偏差精度的参数和误差源 ,提出了减小测试误差。

Based on aerodynamic theory, the article elucidates the characteristics of the shockwave around a supersonic projectile and its utilization——principles of projectile target deviation measurement. It analyzes the parameters affecting target measutement accuracy and error sources causing target deviation. It also provids ways to lower the target measuring system error and to improve its accuracy.
