一种船用矢量水听器的低噪声动态检波电路设计
资料介绍
传统船用矢量水听器的检波电路存在低分贝噪声分辨率低的问题,在噪声低于2 dB动态范围中,传统水听器检波电路内部的算法无法放大噪声信号,导致检波电路无法对信号做出正确判断。针对上述问题,文章提出一种船用矢量水听器的低噪声动态检波电路设计。在通过对低噪声环境的数据分析,对检波噪声信号进行建模计算;根据模型设计检波电路形态;完成电路设计后,导入动态检波算法,完善检波电路的动态低噪声的检测功能。最后,设计仿真实验对设计的电路进行测试。通过对比结果证明设计电路的可操作性。
The detection circuit of the traditional marine vector hydrophone has the problem of low noise resolution.In the dynamic range of noise less than 2 dB,the internal algorithm of the traditional hydrophone detection circuit can not amplify the noise signal,resulting in the detection circuit can not make a correct judgment of the signal.In view of the above problems,this paper presents a low noise dynamic detection circuit design of marine vector hydrophone.Through the data analysis of low noise environment,the detection noise signal is modeled and calculated;the detection circuit shape is designed according to the model;after the circuit design is completed,the dynamic detection algorithm is introduced to improve the detection function of the detection circuit.Finally,a simulation experiment is designed to test the designed circuit.The comparative results prove the operability of the designed circuit.
