本文提出一个研究海洋声传输信道随机时变特性的脉间相关法。导出了周期脉冲经声信道传播的脉间相关函数的表达式,给出了声传播信道和固定目标反射信道脉间相关系数的测量结果,并对信道模型和测量结果作了初步分析。
In this paper, we propose a pulse-wave correlation method to study the stochastic time-varying characteristics of ocean acoustic transmission channels. The expression of the inter-pulse correlation function of the periodic pulse propagating through the acoustic channel is derived. The measurement results of the correlation coefficient between the acoustic propagation channel and the fixed target reflection channel are given. The channel model and the measurement results are also analyzed.
