自航式声诱饵的艇载短基线阵定位方法研究

Study of Location Method for Self-propelled Acoustic Decoy Based on Short Baseline Array

针对自航式声诱饵的战术使用特点和潜艇艇型特点,探讨利用艇载式短基线测量阵对其进行定位的方法;并对短基线测量系统的组成功能和阵形进行初步设计。还研究短基线测量阵的定位解算方法;并对典型工况下的测向误差分布进行仿真分析。仿真结果表明,系统在5 km范围内的测向精度优于1°,能满足自航式声诱饵海上对抗效果的评估需求。

According to the tactical use of self-propelled acoustic decoy and submarine characteristics, the location method of self-propelled acoustic decoy based on short baseline array is discussed, and the short baseline array system＇s function and array are designed. The Short baseline array＇ s position calculating method is also studied, and analysed direction-finding error distribution of typical working conditions. The simulation results show that di- rection-finding precision of the system is better than 1 degree within 5 km range , that can satisfy the countermeas- ure efficiency assessment requirements of the self-propelled acoustic decoy.
