title: [Mechanisms of determining target locator velocity by dolphins and technical applications in hydrolocation and radiolocation].
abstract: 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.
