[Mechanisms of determining target locator velocity by dolphins and technical applications in hydrolocation and...

Dolphin's (Tursiops truncatus) capacity to discriminate between dynamic characteristics of the object location (the target moving radially) was studied. The dolphin sensitivity thresholds for target velocity (2.6 cm/s) and for target acceleration (0.6 cm/s2) were measured. It has been shown that the animal emits two-pulse probe signal to locate the target moving with constant velocity, or three-pulse probe signal--to locate the accelerated target. New highly efficient technical methods of hydro- and radiolocation were suggested on the basis of these peculiarities.
