摘要
在地球为圆球体的假设条件下,为了实现巡航导弹飞行航迹对威胁区的有效规避,提出了基于球面几何计算方法的飞行航迹与威胁区相对位置的判定方法,并给出了相应的判定步骤;通过实例计算,证明该方法能够准确地计算出飞行航迹与威胁区的相对位置,为在地球为圆球体的假设条件下进行航迹规划提供了参考。
Under the hypothesis that that the earth is sphere,flight path needs to avoid the threat.Method of estimation on opposite position between path and threat is proposed based on the calculation method of spherical trigonometry.The estimation steps are also given.Through emulation calculation,it is proved that this method can estimate the opposite position between path and threat exactly.Reference can be provided to path planning under the hypothesis that the earth is sphere.
