【摘要】 针对海洋石油管线探测多波束剖面声纳的高速、大容量的实时信号处理任务,以及声纳系统进一步扩展的需求,设计并实现了一种基于IP网络互连的、以并行DSP为处理节点的多波束剖面声纳系统。该系统应用于海底石油管线探测与定位,系统中的每个处理节点与数据采集转换部分采用TCP/IP网络连接,可以通过物理上添加一个或多个处理节点成倍的提高系统的信号处理能力,而在软件上无须大的改动。通过电联调与水槽试验,验证了系统的可行性和稳定性,该设计为高速水声阵列信号实时处理系统提供了一种全新的解决思路。更多还原

【Abstract】 As a high-speed and high-capability real-time system,a multi-beam chirp sonar based on IP connecting and DSP processing node is proposed and designed.The system is applicable in seabed petroleum pipeline detection and orientation.Every node of the chirp sonar connects with data conversion through TCP/IP.With one or more nodes added,the processing ability of the system can be geminated without changing the software.Debugging and flume examination show that the system is feasible and steady.This design provides a new method for the high speed multi-beam sonar.更多还原
