摘　　要：惯导飞行段的符合是末制导炮弹射表编拟工作中的关键技术难题,通常编射表的对象都是无控弹,有控弹道符合问题是射表编拟首次遇到的课题。简要介绍了惯导飞行控制原理及惯导段弹道数学模型,确定了符合系数和符合对象,介绍了POWELL法和单纯形法的基本思路、方法,并进行了符合计算。通过利用符合结果计算的弹道三维坐标值和实测值比较,单纯形法效果较差,而POWELL法效果很好,不仅落点一致,而且惯导段弹道形状也吻合得非常好,充分说明基于POWELL法的惯导飞行段符合方法是有效可行的。此方法充分利用惯导段三维坐标测量信息校准弹道模型中较多的关键参数,在高价值制导弹药射表编拟方法研究中实现了突破。In the inertial navigation segment of terminal-guided projectile,coincidental calculation is a key technical problem to be dealt with in firing table compilation in which the object is non guided,and it is also the first issue encountered to compile guided projectile.The principle of inertial navigation control and ballistics mathematics model are introduced,the coincidence coefficients and coincidental calculation object parameters are determined.Powell method and simplex method are introduced and used for coincidental calculation.By comparing the 3D coordinates of trajectory calculated from the coincidental calculation result and 3D coordinates measured values,the effect of the simplex method is more poor,and the Powell method is better.Not only the impact points consistent,but also the trajectory shape is identical.This fully illustrates that the Powell method is effective and feasible for coincidental calculation in inertial navigation segment.This method makes full use of inertial navigation segment 3D coordinates information to key calibrate the parameters in ballistics model,and has achieved a breakthrough in the research on high value guided munition firing table compilation.
