为提高落点密集度,一维弹道修正弹采用增阻方式对射程进行修正,在射击距离上增加扩展量计算发射诸元,射程扩展量若取大或取小都不利于落点密集度。为确定一维弹道修正弹对海上目标射击的最佳射程扩展量,在研究射击原理和射击误差的基础上,建立了射程扩展量的计算模型。仿真计算表明:依照此模型计算射程扩展量,修正后具有最多的命中弹数。

To improve the concentration of projectiles, the range was adjusted by drag brake for one-dimensional trajectory correction projectile. The firing collimation angle was calculated with the extended range and the distance between the gun and the hit point. The concentration of projectiles would be declined if the extended range is longer or shorter. In order to get the optimal extended range when one-dimensional trajectory correction projectile firing at sea target, firing principle and firing error were researched, and the model of calculating the extended range was set up. It is proved by simulation that the maximum shell hits are gained after amendatory set works if the extended range is calculated with the model in the paper.
