摘要
在导弹弹道计算过程中,需要经常使用坐标转换。通过分析导弹常用空间直角坐标系之间的关系,建立了空间直角坐标系之间的旋转变换方法,编制了通用算法库,并结合算例验证了该算法的可行性和正确性。该方法以简单的形式描述了各坐标系之间的转换关系,易于编程实现,可作为导弹弹道相关研究工作的坐标转换基础工具使用。
In missile trajectory calculation, coordinates conversion is commonly used. With the help of the analysis on the relationship of missile common space rectangular coordinates, the rotary conversion method among space rectangular coordinates is established and common algorithms library is programmed. The fea- sibility and correctness of this method are verified with examples. This method describes the conversion re- lationship among coordinates in a simple form and is easy to be realized by computer. It can be used as a base tool of coordinate conversion for the research work of missile trajectory.
