发明名称 CONNECTION OF IONOSPHERIC RADIO SYSTEM
摘要 Ionospheric radio system connection arrangement solves the technical problem of interference suppression in double-beam radio signal propagation by hop from ionosphere onto amplitude of demodulation signal. The principle of the ionospheric radio system connection arrangement consists in the fact that output of the first frequency modulator /3/ is connected with the first input of the combiner /5/ and the output of the second frequency modulator /4/ is connected with the second input of the combiner /5/. Ionospheric radio system connection arrangement can be utilized for radio connections via hop from the ionosphere zones.<IMAGE>
