Development of an active sonar array signal monitoring system

A signal processor based active sonar array signal monitoring system is developed and introduced in this paper. The system functions include array test, acoustic spectrum measurement, directivity measurement, amplitude-phase consistency measurement and reverberation level measurement. This paper first introduces the system hardware platform, software platform and system functions; then introduces the design process of the main modules and the implementation in detail; and finally gives the analysis results of the recorded signals by the system. The application shows that the system is stable and reliable, easy to use, fully functional, and it can greatly improve the efficiency of developing and testing.
