- Abstract
A model of click production in a dolphin is considered on the basis of analogy with a traveling-wave antenna focused in a given direction. Calculations show that signals deviating from the principal direction of radiation are distorted, so that the forepart of such a pulse is stretched in time while the amplitude of the pulse decreases. A pulse emitted sideways is ahead of the corresponding pulse emitted in the principal direction. A possible mechanism of short pulse production by the sounding organ of the dolphin is considered in terms of the radiation model based on the traveling-wave antenna. The mechanism consists in partial transformations from kinetic energy to elastic and back in the corresponding oscillatory system. A possibility of testing the dolphin for the presence of such a mechanism by a noninvasive experimental technique is pointed out.
