摘要
该文分析了弹道靶道测量中的精度问题及通常使用的静态检测方法,并针对静态检测与靶道实测相差甚远的问题,提出了一种动态检测方法.该方法充分考虑到弹道靶道的测量对象是高速飞行体以及照片质量、气流附面层、发射时的恶劣环境和振动等因素对测量精度的影响,结合误差理论,给出了动态精度的计算公式,在已建成的IB-12中间弹道靶道中应用,效果良好.
This paper analyses the problems of precision and usually used static stateexamination method in Ballistic Range measurement.A dynamic state examinationmethod is put forward,which is directly aimed at the problems that the prediction ofstatic state examination is far away from the situation of real Bllistic-Rangemeasuring.A dynamic state examination method takes full account of influences suchas measuring objective of Ballistic-Range (high speed flying body as high as v=1500～2000 m/s) and photographic quality,gas flow bounday layer,adversesurroundings,vibration and so on.Combining with error theory,this method gives acount formula of the dynamic state precision which was applied in IB-12 IntermediateBalistics Range and a good result was achieved.
