几种常用水声信号的特性研究
Research on Properties of Several Common Underwater Acoustic Signals
摘要
Abstract
Underwater acoustic signal is the major information carrier of the underwater navigation and location and communi-cation.It is important to research the properties of underwater acoustic signal.The continuous wave signal and linear frequency mod-ulation signal and hyperbolic frequency modulation signal are the common signals used in the underwater.The time domain and fre-quency domain and the power spectral density of the three signals are investigated.The ambiguity function,ambiguity scale,ξ=0 and τ=0 sections of the ambiguity function are computed by simulation.The autocorrection function and the wavelet time-frequen-cy analysis of these three signals are researched.The research results show that the experiences match well with the theory value.关键词
