[Model of the system for stabilizing the frequency of the echosignal of the Rhinolophus locator].
Physical analysis of anatomic, physiological and behavioural data pertaining to the work of Rhinolophidae echolocator is carried out, results of spectral analysis of its probing impulse are analysed. On this basis the working mechanism of sound emitting apparatus is proposed. A phenomenological model of the frequency stabilization system of the signal reflected from a located object is constructed. This stabilization is carried out by the compensation of Doppler shift of the echo frequency by a change of the generated impulse frequency. Due to the application of a differential method the model provides for potential accuracy of tuning, and its work does not depend on the value of a reflected signal and its sufficiently small changes which is in agreement with the experiments.
