| 中文摘要: |
| 针对长线阵易发生阵形畸变问题，提出一种基于非声传感器和水动力模型求解的联合阵形估计系统。该系统在充分利用非声传感器信息的基础上，进一步根据拖线阵水动力模型，求解实时阵形，实现阵形估计。仿真实验及数据分析表明，与传统的阵形估计算法相比，该系统的估计精度提高10%以上，对工程实践具有较高的指导意义。 |
| 英文摘要: |
| This article proposes a combined shape estimation system of long linear array based on non-acoustic sensor method and hydrodynamic model solving method.The system makes full use of the non-acoustic sensor information to further solve real-time array shape of the tactical towed array according to the hydrodynamic model.Through the data analysis,this system's estimate accuracy can be increased by more than 10% compared with traditional array shape estimation algorithm,which has a higher guiding significance to practical engineering applications. |
