Acoustic propagation

An example of head wave propagation from a bottom located acoustic source to a vertical array of receivers. The acoustic signal is totally reflected at the sea surface and partially transmitted at the sea bottom interface generating a seabed compressional wave. The wavefronts cross the array at successive times and arrival angles according to the various reflections generating the so-called arrival pattern fully characterising the environment through which the signal has propagated. That is the basis of environmental-based underwater signal processing developed at SiPLAB. This animation was obtained by O. Rodríguez using an acoustic model (for more information see other models).
