Prediction of the beamformed acoustic ray arrival structure for the 1992 Barents Sea coastal tomography test

In an effort to solve the forward propagation problem associated with the 1992 Barents Sea Polar Front Experiment Tomography Test, the transmission of a 224 Hz pulse signal from a near bottom sound source to a vertical hydrophone array was simulated based on three-dimensional ray theory. based on th...
