外弹道数据处理中航向角精确计算方法

针对国内靶场在外测事后数据处理中航向角计算存在的问题，深入分析了传统计算方法存在的缺陷，提出了两种新的航向角计算方法——坐标法和速度法，并提供了两种方法的算法和模型。在理论分析的基础上，采用实测数据对新旧三种方法比较分析，最后验证速度法是目标瞬时航向角最佳计算方法。

A Method for Accurate Heading Angle Calculation in Metric Data Processing

With regard to the problem of heading angle calculation in metric data processing,defects of traditional calculation methods are deeply analyzed.Two new heading angle calculation methods coordinate method and velocity method are proposed,together with the respective algorithms and models.Based on theoretical analysis,actual measurement data is used in comparison between the three existing and new methods.It is demonstrated that the velocity method is the best for calculation of the instantaneous heading angle of target.
