资料介绍

矢量水听器用于检测水下声音信号,但其输出信号微弱,易被复杂的海洋环境噪声干扰,不能直接用于后续采集电路,为了实现对矢量水听器检测到的水下声音信号进行有效提取,针对水听器输出信号的特点,设计了一种相应的调理电路,使得后续采集电路可以得到较高信噪比的信号,通过对其进行仿真和实际测试,验证了该调理电路的可行性及有效性。

Vector hydrophone can be used to detect underwater sound signal,but the output signal is weak and vulnerable to be influenced by noise in the ocean environment,it can't be directly used for subsequent collecting circuit. In order to achieve collecting underwater signal which is detected by the vector hydrophone efficiently,a corresponding conditioning circuit is designed according to the output signal characteristics in this paper to achieve a higher signal-to-noise ratio for the subsequent collecting circuit. Validated by software simulation and practical tests that the conditioning circuit is feasible and effective.
