摘要

针对导弹试验,在进行弹道参数解算时,需要提供精确的发射方位角的问题,采用高斯投影的方法,详细推导了一种不同于传统的发射方位角计算方法,并提供了具体算法和模型.在理论分析的基础上,采用新方法对算例数据进行计算和分析.结果表明,用新方法计算得到的发射方位角精度达到秒级.该方法已在靶场发射方位角的计算中得到成功应用.%In ballistic missile flight test, when calculate trajectory parameters, it is need to give accurate launching azimuth. Unlike conventional methods, a new method of calculating launching azimuth based on Gauss projection is presented. A detailed algorithm and model for the method are presented. Following theoretical analysis, experiment data is used in calculation and analysis with the new method. The results show that the launching azimuth calculation accuracy of the new method reaches second level. The method is already successfully used in calculation launching azimuth at a test range.
