一种通用声呐信号源的设计

摘要

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.%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。
