为快速精确的预报弹丸落点,提出了基于高维插值的末修弹落点预报方法。在介绍高维插值法的基础上,以末段弹道参数为离散点,对其高维插值,得到落点预报显示方程,并利用显示方程进行落点预报仿真测试。仿真结果表明,该方法预报落点的精度较高,且平均预报时间为3.508ms,比数值积分法少709.3933ms。因此,采用高维插值法预报落点是有效可行的,可为实际应用提供参考。

In order to predict impact point of projectile fleetly and accurately, a method based on multidimensional interpolation for impact point prediction (IPP) of terminal correction projectile was put forward. Display equation of IPP was built with terminal ballistic parameters by multidimensional interpolation. Then, IPP based on multidimensional interpolation was simulated. The result shows the precision of this prediction method is higher, and the average forecast period is 3.508 ms. Compared with numerical integration for IPP, forecast period upon multidimensional interpolation is much shorter. Therefore, the method based on multidimensional interpolation for IPP is feasible.
