[edit] Summary

"Acoustic simulation in a simple ocean environment, depicting several of the features required in a Naval operational model: beam source, wind-driven sea surface losses on the first reflection, and loss-vs-angle ocean bottom treatment. Also present but less evident in the simulation are seawater volume attenuation and spherical Earth corrections. Source frequency, angle, and beamwidth are 250 Hz, 5 degrees, and 1.5 degree respectively; water is isovelocity at 1500 m/s and depth is 1000 meters; windspeed is 20 m/s; ocean bottom parameters approximate soft rock."
