Annotation According to rigorous method of “related” fields the analytical expressions to describe electric fields of cylindrical piezoceramic radiators, forming flat echolocation system was obtained. As a result of numerical analysis the quantity relations and the features of frequency characteristics of the electric current and the input impedance of plane system was obtained and their physical interpretation was given. It is shown that the radial symmetry of the electric load system of radiators and the loss of radial symmetry of the acoustic load of radiators in this system violates the identity of the electronic processes occurring in the piezoelectric elements in the system.
