基于声级测量的水声接收机设计与实现

随着现代降噪技术的发展,水中舰艇的噪声级越来越低,使得目标信号越来越微弱。本文设计了一种估计水中舰艇的声源级,同时不失去水中舰艇辐射噪声的有效信息的水声接收机,采用四路检波和电平提升电路,经过单片机MSP430F5438的处理,得到目标声源级。采用该方法设计的接收机结构简单,性能可靠,功耗低,实时性好,满足现代水下自主检测系统的需求。

Design and implementation of a new hydroacoustic receiver based on source level measurement

Due to the development of noise reduction technology,the noise level of naval vessels is becoming lower and lower,which leads to the attenuating signal intensity.In this paper,a new hydroacoustic receiver is put forward which can retain information of target radiation noise as well as estimate target source level through quadruple detection and level amplifying circuit and SCM MSP430F5438 processing.This new design has a simple-structure,reliable real time performance and low power consumption,which can meet the requirement of modern autonomous detection system.
