摘　　要：设计了一种带有直流伺服的水声信号接收电路,主要解决电荷放大型水声信号接收电路在环境噪声、温度变化以及水压偏置等因素的影响下产生直流偏置,进而导致水声信号堵塞的问题。引入直流伺服电路,通过负反馈机制实时调节输入信号和输出信号之间的差异,从而提高了接收电路的稳定性和准确性。该设计能够有效抑制低频干扰,具有更好的动态特性,为该领域的研究和应用提供了可供参考的技术手段。An underwater acoustic signal receiving circuit with DC servo is designed,which mainly solves the problem that the underwater acoustic signal receiving circuit with charge amplifier generates DC bias under the influence of environmental noise,temperature change and water pressure bias,which leads to underwater acoustic signal blockage.The DC servo circuit is introduced to adjust the difference between input signal and output signal in real time through negative feedback mechanism,thus improving the stability and accuracy of the receiving circuit.This design can effectively suppress low-frequency interference and has better dynamic characteristics,which provides a reference technical means for research and application in this field.
