摘要

摘要: 为评估光纤光栅水听器拖曳线列阵基本声学性能及其抗加速度和抗流噪声能力，研制了光纤光栅水听器拖曳线列阵湖试样阵。详细描述了光纤光栅水听器拖曳线列阵湖试样阵的结构，介绍了光纤光栅水听器拖曳线列阵湖上动态拖曳试验系统组成、试验方法和结果，分析了试验数据，试验结果显示超细缆径的光纤光栅水听器拖曳线列阵在动态拖曳条件下，接收的单频信号具有40 dB左右的信噪比，展现了在鱼雷等小平台上实现拖曳指导的应用前景。

Abstract: For the purpose of evaluating the acoustic characteristics of the fiber grating hydrophone towing array as well as its capability of eliminating the effects of acceleration and flow noise, a prototype of the array is developed. The configuration of the prototype is demonstrated. Subsequently, the experimental system is introduced, and the experimental methods and results are discussed. Finally, the experimental data is analyzed. It is shown that in the condition of dynamical operation the fiber grating hydrophone towing array with very small fiber cable diameter can detect single frequency signals whose signal to noise ratio(SNR) is about 40 dB, which implies a bright prospect for the arrays to be applied in such small carriers as torpedo.
