摘要:

海上弹着点位置测量是海上靶场舰炮武器精度试验中非常关键的一步, 对加强靶场建设、提高部队战斗力具有重要意义。采用被动声探测技术, 在单三元阵定位基础上进行布阵方式的改进, 提出了一种基于双十字阵的海上弹着点定位方法, 推导阐述了定位原理, 重点对三元阵定位与双十字阵定位做出了详细的误差分析与仿真。最终得出, 在假设的理想算例情况下, 基于双十字阵的弹着点定位方法的定位误差降低为单三元阵定位的4.66‰, 更好地满足了海上弹着点定位需求, 具有一定的应用价值与发展前景。

Abstract:

The measurement of the position of the impact point at sea is a key step in the precision test of naval gun weapons in the sea shooting range. It is of great significance for the construction of the shooting range and the improvement of the combat effectiveness of the army. The passive acoustic detection technology is used to improve the array arrangement mode based on the single three-element array positioning, and a marine impact point positioning method based on dual cross-array is proposed. The positioning principle is deduced and described, with emphasis on the detailed error analysis and simulation of three-element array positioning and dual cross-array positioning. Finally, it is concluded that under the ideal example assumed in this paper, the positioning error of the impact point positioning method based on dual cross-array is reduced to 4.66‰ of that of the single three-element array positioning method, which better meets the requirements of impact point positioning at sea, and has a certain application value and development prospect.

Key words: location of impact point at sea, sensor array, dual cross-array, underwater acoustic passive location, error analysis and simulation
