舰炮一维弹道修正弹射击误差分离和校正研究

由于工作原理不同，传统无控弹射击校正方法不适用于一维弹道修正弹。分析了舰炮使用一维弹道修正弹射击误差构成和射击观测特点，提出一维弹道修正弹射击校正新方法，首先通过修正机构不工作，利用观测弹着点相对预测弹着点偏差平均值校正火控设备预测弹着点误差；然后利用修正弹正常工作时观测弹着点相对目标（或提前点）偏差平均值校正修正机构误差。假设各误差值，通过解弹道方程仿真计算表明，按新方法射击校正能够显著提高射击精度。

Research on Separating and Correcting Firing Errors of One Dimension Trajectory Correction Projectile Fired by Shipborne Gun

The conventional firing correction method of bomb without control is not fitting for one dimension trajectory correction projectile because their work theory are different.Firing errors and firing detection were analyzed when shipborne gun fired correction projectile,and the new firing correction method was demonstrated.Firstly,the forecasting point of fall error of fire control equipment was corrected with the average deviation between detecting point of fall and forecasting point of fall when damping ring didn’t work.Secondly,the correcting error was corrected with the average deviation between detecting point of fall and target or predicted point when damping ring work normally.It is proved that the new firing correction method can improve firing accuracy by simulating with computing trajectory equation and supposing every firing error data.
