A High-precision Measurement Method of Full Ballistic Flight Time of Projectile

为解决兵器试验中弹丸全弹道飞行时间测量时地形地貌复杂、弹道线长、首落区地域时差、传输信号弱等因素对测试结果影响的问题,提出一种以卫星授时为基础的高精度弹丸全弹道飞行时间测量方法。简介试验测试系统的组成、工作原理及测试操作流程,并通过某型号火箭弹外场试验测试及数据分析验证该系统的布局合理性、操作可行性及测试高效性。试验结果表明,该测试系统设计简单可靠、性能稳定、测量数据准确,弹丸飞行时间的测量精度约为1ms。

In order to solve the problem of the impact of factors such as complex terrain and geomorphology,long ballistic lines,geographical time difference in the first landing area,and weak transmission signal on the full ballistic flight time measurement in weapons test,a high-precision measurement method of full ballistic flight time of projectile based on satellite is proposed.This paper summarizes the composition,working principle and test operation process of the test system,and verifies the layout rationality,operational feasibility and test efficiency of the system through test and data analysis.The field test of a certain type of rocket is conducted and the test results show that the test system is simple and reliable in design,stable in performance,accurate in measurement,and the measurement accuracy of projectile flight time is about 1 ms.
