水声信道的多模型模拟和试验

Multi-Model Simulation of Underwater Acoustic Channel

水声信道是一个时变的多径信道,且在不同的时间由于海面的状况不同而不同。为较好地实现水声通信,必须对各种水声信道进行较好地了解,研究出适合水下通信,尤其是水下实时通信的较为实际的模型,增加水下声通信的可靠性和水声实时通信的可懂率。该文在前期研究的基础上,将多模型方法应用于水下声信道的研究,并得出了相应的实验方法。

Underwater acoustic channel is a time-varying multipathing channel. It varies due to different season, different area and different situation of sea surface. For realizing real underwater communication, characteristic of underwater channel must be mastered to create the model of underwater channel in order to improve the reliability and understandability of underwater real communication. On the basis of earlier research, the method of multiple model and its experiment have been introduced in this paper for researching the characteristic of underwater acoustic channel.
