    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.
