大口径火炮对海射击弹着点检测激波定位模型

Shock Wave Position Model of Impact Point for Heavy Caliber Artillery Firing to Sea

对海射击受能见度、目标运动等因素的影响,弹着点检测困难。针对激波稳定性好、受环境因素影响小等特点,提出了一种弹着点检测的激波定位模型,利用试验方法确定弹丸系数,利用传感器阵检测弹道激波,利用射弹飞行时间和落速确定弹道入射方向,综合激波到达时间差和传感器之间的几何关系,从而实现单发弹着点、弹群射的精确检测,将弹着点定位精度提高到10 m范围之内,检测可靠性大于95%。能够用于大口径火炮对海间瞄射击弹着点检测和实弹射击成绩评定,为炮兵对海射击弹着点检测提供了一种准确、有效手段。

Because the facts including visibility and target moving effect firing to sea,impact point measurement is difficult.Aiming at the characteristic of good stability and less affected by environment of shock wave,the thesis advances a kind of shock wave position model of impact point.The model applies the experiment method to confirm projectile coefficient,uses sensors matrix to measure ballistic shock wave and utilizes projectile flight time and terminal velocity to confirm firing direction.Contrasting arrive time and geometrical relationship among the sensors,the model realizes to accurately measure impact point of single-shot fire and group-shot fire,Which advances the measurement precision of impact point to 10 m and reliability to 95 percent highly.The model can be used to measure impact point and evaluate ball firing grade for heavy caliber artillery firing to sea,which provides a precise and valid means for artillery firing to sea to measure impact point.
