摘要 针对一维弹道修正引信阻力机构增阻能力有限的问题,采用概率与数理统计方法,以落入指定幅员区域弹丸数量最多为原则,对一维弹道修正弹药所需提前瞄准量、最大射程修正量进行分析.研究结果表明,采用只对部分弹丸进行修正,提前瞄准量是所需最大射程修正量的1/2,且为无修正弹丸落点纵向误差标准差2倍左右时,修正策略为最佳选择.以某155mm榴弹对象,进行蒙特卡洛打靶仿真分析,验证了该修正策略的正确性.该修正策略能以较小的提前瞄准量及所需最大射程修正量,使射程精度得到最大程度的改善,特别适用于阻力机构增阻能力有限的一维弹道修正引信. Determination of aiming advance distance and maximum correction distance is important for the correction strategy on one-dimensional trajectory correction projectile. Focusing on the problem that the resistance device of one-dimensional trajectory correction fuze has limit increased-resistance capacity, the aiming advance distance and required maximum correction distance were analyzed using probability and mathematical statistics based on the principle of the maximum number of projectiles that fall into the designated field. Results show that, when parts of the projectiles are corrected, the correction strategy is the best in condition that the aiming advance distance is half of the maximum correction range and 2 times of the standard deviation of range error of uncontrolled projectile. Taking 155mm shrapnel as an example, the reasonableness of the correction strategy above has been verified using Monte-Carlo simulation. With small aiming advance distance and the maximum range correction, the proposed correction strategy can make the greatest improvement of the range accuracy. Therefore it is perfect for one-dimensional trajectory correction fuze which has limited resistance capacity.
