基于虚拟仪器海上通信系统设计

Design of maritime communication system based on virtual instrument

为了满足海上通信系统特点的要求,系统采用虚拟仪器技术,通过数据交换统一集中管理有效地解决了大容量数据无线传输难题。基于匹配滤波复合信号检测技术有效地抑制了水声信号多途、混响对海上通信系统的影响,降低了水声信号瞬变引起的信号分裂导致系统漏报、漏发概率。基于虚拟仪器技术开发的海上通信系统不仅开发周期短,而且便于系统进行二次技术升级和功能扩展等优点。

To satisfy the characteristics requirement of the maritime communication system, the virtual instrument technology is adopted in the system. The problem of large capacity data wireless transmission was solved effectively by uniform centralized management of data exchange. The composite signal detection technology based on matched filtering can effectively restrain the influence of multi-path and reverberation of the underwater sound signal on the maritime communication system, and reduce the system＇s false alarm rate and missing alarm rate due to signal splitting causing by the underwater acoustic signal transient. The developed maritime communication system based on virtual instrument technology has short development period, and is easy to proceed secondary technology upgrade and function extension.
