A new type of Doppler velocity sonar receiver

针对小型化多普勒测速声呐接收机的要求,设计并实现一种基于集成模拟前端(AFE)的多普勒测速声呐接收机。本文从工程实际需求出发,结合传统接收机电路设计方法,提出一种基于集成模拟前端的声呐接收机设计方案,并进行仿真和实物测试实验。实验数据表明,AFE接收机与传统接收机电路板相比面积减小71.3%,使用该系统解算出的频移值偏差较小,满足多普勒测速声呐系统要求。

Aiming at the requirement of miniaturized Doppler velocity sonar receiver,a Doppler velocity sonar receiver based on integrated analog front end(AFE)is designed and implemented.Based on the actual needs of the project,this paper proposes a sonar receiver design scheme based on the integrated analog front-end based on the traditional receiver circuit design method,and conducts simulation and physical test experiments.The experimental data shows that the area of the AFE receiver is reduced by 71.3%compared with the traditional receiver circuit board,and the deviation of the frequency shift value calculated by the system is small.Meet the requirements of Doppler velocity measurement sonar system.
