摘要
针对近炸引信验收中天幕靶测试脱靶量遇到的误差偏大的问题,在分析天幕靶工作原理的基础上,采用理想平面弹道模型与数值仿真分析相结合的方法,研究了天幕靶直线弹道模型存在的原理误差及其变化规律.给出了一定条件下通过数据修正方式改善天幕靶测试精度的计算公式.
During the acceptance check of proximity fuse,apparent measurement errors are often found in the miss-distance measurement by sky screens.Based on a brief introduction to the operating principle of sky screen,and using the ideal plane trajectory theory and Monte Carlo method,aprinciple error existing in the simplified sky-screen linear trajectory model and its properties are investigated.A method for improving sky screen＇s measuring precision is introduced.The feasibility of this method under certain conditions is also proved with some revising formulae presented.
