一种通用声呐信号源的设计

Design of a universal sonar signal source

在设计主动声呐系统时,为了使声呐系统能够在不同的工作环境中达到最佳效果,需要设计相应的声呐波形。采用ADI公司DDS芯片AD9959设计了一种可编程的通用多通道声呐信号源,可生成任意的声呐信号波形,其具有十分重要的应用前景。

In the design of active sonar system,in order to make the sonar system working in different environment achieve the best effect, the appropriate sonar signal waveform needs to be designed. A programmable general multi-channel sonar sig-nal source was designed on the basis of DDS chip AD9959 made by ADI. It can generate arbitrary sonar sigal waveform,and has a bright application prospect.
