Bionic acoustic systems and devices

The biosensor echolocation system of cetaceans is briefly considered. The general schemes of construction and exci-tation of ultra-wideband antennas, composed of rod two-section transducers with phased excitation, and also transduc-ers waveguide type using the management PC, are resulted. Possibility of reception of a pass-band of an order of 2–3 oc-taves and radiations of these models of echolocation and communication signals of dolphins and Beluga whales, and also - ultra-short acoustic impulses reconstructed on frequency in the specified band of frequencies is shown.
