TRANSMITTING PATH FOR EXCITATION OF HYDROACOUSTIC ANTENNA

摘要

FIELD: antenna equipment.;SUBSTANCE: invention relates to the field of amplification and generator equipment and can be used in transmitting paths (TP) for excitation of hydroacoustic antennae. Disclosed is a transmission path for excitation of a hydroacoustic antenna, in which, instead of parametric method of current stabilization, which has limitations on stability, the principle of automatic control of currents of key power amplifiers is used at changes of value of load in a wide range. This principle allows to ensure high accuracy and speed of control, thus preventing even short-term emission of currents, creating comfortable conditions of power part of TP equipment. In such conditions, power elements can be installed with minimum process margin, which increases specific indices of equipment.;EFFECT: high energy efficiency, reliability and safety of operation in conditions of virtually unlimited change of load impedance, which enables uninterrupted operation of TP in extreme operating modes with preservation of stable characteristics of the output signal, in particular amplitude-frequency characteristic.;1 cl, 4 dwg
