dc.description.abstract | The frequency-dependent spatial and temporal variabilities of sound propagation in coastal regions is investigated by ezperiment and numerical simulations. Experimental observations show that temporal coherence of the propagated broadband signal changes significantly with pulse center-frequency, as well as varying with geographic location and time(i.e., different environments). Numerical simulations of such sound transmissions are carried out by using the full-wave broadband PE model and reasonable agreement with the experimental data is found. | |
