J-15 CW transmission data analysis and comparison with simulation results
Data analysis and 3-D numerical simulations of the acoustic propagation in the ASIAEX SCS experiment are presented in this paper. During the experiment, personnel aboard the Taiwanese ocean research vessel, OR3, periodically deployed and towed the J-15-3 acoustic source to study the sound propagation in the ocean. One of the emitted waveforms was continuous wave (CW), which had 5 simultaneous 140, 260, 340, 452 and 560 Hz. Transmission losses of CW tones are obtained. As for numerical simulations, the wide-angle version of FOR3D is used to calculate transmission losses with background and measured sound speed profile containing internal tides. The model scenario includes also the sediment and 3-D bathymetry. Results of data analysis and numerical simulations show that TL variations in the data are due to the variations in the sediment and water columns.
