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.
