地地导弹天文导航的一种建模方法

介绍了远程地地弹道式导弹采用惯性／天文组合制导方案的优点。提出了以惯性导航为主、天文导航为辅的一种导航方法，推导出该方法对应的导航基准参数计算模型、导航参数计算模型及天文导航系统的横向导引方程。最后通过仿真计算，给出了所提供的天文导航方法和计算模型对提高导弹命中精度的效能。

A Modeling Method of Celestial Navigation of a Ground-to-Ground Missile

The advantage of the IN(Inertial Navigation)/CN(Celestial Navigation) combined guidance method of a ground-to-ground ballistic trajectory missile is introduced in the paper. A navigation method that the IN method is principal and the CN method is subordinate is presented. The calculation model of navigation standard parameter and navigation parameter is deduced. On the basis of the calculationmodel, the cross guidance equation of the CN system is given. At last, effect on the missile hit probability, using the new navigation method and the navigation model, is analyzed by the digital simulations.
