摘要
This paper presents a stochastic model of a turbulent shallow-water acoustic channel. The model utilizes a Monte Carlo realization method to predict signal transmission conditions. The main output from the model are statistical descriptions of the signal-to-multipath ratio (SMR) and signal fading, Probability density functions of signal envelope are evaluated by Pearsons's Skew-Kurtosis Chart, generally predicting Ricean fading, Dynamic calculations of SMR by the model overcome the main inconveniences of deterministic calculations, providing "smooth" instead of "noisy" curves as a result. Dynamic calculations of SR IR and fading are concluded to provide more intelligible and realistic results than deterministic calculations.
