水下爆炸试验爆源定位方法研究

Research on Positioning Method of Underwater Explosion Source

为实现水下爆炸试验爆源在爆炸时刻相对于水面目标舰艇的定位测量,提出一种最小误差逼近的遍历搜索定位方法。该方法通过在目标舰艇上安装一定数量的爆炸载荷压力测量传感器,根据获取的爆炸载荷数据中冲击波传播的时间信息和冲击波压力峰值,实现爆源定位计算。小当量的水下爆炸试验结果表明:4个有效爆炸载荷测点数据可以实现爆源炸点定位计算,增加有效测点数量,可以提高爆源定位精度。

To realize the allocation measurement of the explosion source to the target warship, a traversal search method through minus error approaching was proposed. By mounting definite amount of explosion pressure sensors on- to the target warship, the positioning of the explosion source was calculated based on the transmission time and peak pressure of the shock wave ,which was obtained from the explosion measured data. Results from small equivalent ex- plosion test showed that positioning of the explosion source was obtained by setting 4 effective pressure measuring points, meanwhile, the precision of the positioning increased by raising the number of the measuring points.
