3-D Gaussian Canyon - Broadband pulse

 3-D Gaussian Canyon - Broadband pulse

Propagation of a sound pulse in a three-dimensional Gaussian canyon waveguide (fully 3-D computation).

The source signal is a Hanning-weighted four-period sine pulse (center frequency: 25 Hz; bandwidth: 40 Hz). The acoustic point source is located in the water column at range r = 0 and at a depth of 40 m. The signals were multiplied by r to compensate for spherical spreading.
