摘要
提出一种基于Compact RIO嵌入式系统的声信号处理模块,用以实施信号采样、存储及处理各种不同类型的模拟信号,通过结合Compact RIO高速数据处理能力和Lab VIEW图形化开发环境,实现实时水声信号采集、处理,并应用于超短基线定位系统中。水下定位试验验证了模块的可行性和实用性,定位精度满足系统设计要求。
This paper presents a sound signal processing module based on Compact RIO embedded system, which is used to implement signal sampling, storage and processing of various types of analog analog signals. Through the combination of Compact RIO high-speed data processing capability and LabVIEW graphical development environment, real-time underwater acoustic sig- nal acquisition and processing is realized, and it is applied to ultra-short baseline positioning system. Each module of the system of signal processing is discussed and the lake experimental validated the practicability of the system. The underwater positioning test verifies the feasibility and practicability of the module, and the positioning accuracy meets the system design requirements.
