摘要
方位角初值的确定对诸元计算的快速性有很大的影响。讨论了3种初值确定方法:不考虑地球旋转的初值确定,考虑地球旋转的初值确定和考虑主动段弹道变形的初值确定。其中考虑主动段弹道变形的初值确定方法是在对弹道特性分析的基础上首次提出的。通过算例分析,考虑主动段弹道变形的方位角初值在所有情况下都能给出较好的估计。
The Initial value of azimuth has a vital effect to the rapidity of data calculation. Three methods are discussed including initial value evaluation without regard to earth rotation, initial value evaluation with earth rotation and initial value evaluation with ballistic deformation considered. The last method is put forward for the first time, based on trajectory characteristics. An example is given to show the method with ballistic deformation considered can give precise evaluation in every direction.
