Android系统在弹道仿真分析中的应用研究

Application Research of Android System in Ballistic Trajectory Simulation Analysis

为了满足野外靶场方便地进行弹道仿真预测及对实验弹道数据进行分析的需求,基于当前主流的Android平台,通过建立6DOF的刚体弹道模型及卡尔曼滤波预测模型,设计了基于Android平台的弹道仿真计算及数据分析软件,实现了弹道计算、试验数据分析等功能。研究结果表明,基于手机硬件平台与基于Windows平台的弹道仿真软件计算结果精度一致,在保持精度前提下实时性稍有下降,且经卡尔曼弹道滤波后,能有效剔除测量弹道参数的噪声。研究结果可为相关领域提供一定参考和借鉴。

In order to satisfy the demand that ballistic trajectory simulation prediction and analyze experimental data can be conveniently achieved,the 6 degrees-of-freedom（ DOF） rigid trajectory model and the ballistic model of Kalman filtering is established by using mainstream Android portable apparatus.Simulation calculation of ballistic trajectory and experimental data analysis software is designed on Android operation system to achieve calculation of ballistic trajectory and experimental data analysis. The results show that the same precision of calculation is achieved on the Android operation system and the Windows operation system,but the real-time is reduced under the precondition of precision. The measurement noise can be decreased greatly by Kalman filtering. All the results offer reference for other related area.
