Abstract: 1. Meteor radio communication technique, characterized in that both the "hot" zones of meteor combustion region are being irradiated by directed VHF - radio radiation from both the points of radio path, when echo signals from the ionized trace of the burnt-out meteor appear, communication is established and information interchange is accomplished, wherein meteor combustion region is irradiated by radio radiation with circular and/or elliptic polarization. 2. Meteor radio communication technique, characterized in that the "hot" zones are irradiated under conditions of conical radiation, adequate to cross dimensions of the zones. 3. Meteor radio communication technique, characterized in that both the "hot" zones of meteor combustion region are being irradiated by directed VHF - radio radiation from both the points of radio path, when echo signals from the ionized trace of the burnt-out meteor appear, communication is established and information interchange is accomplished, wherein the solid angle of directed VHF - radio radiation is limited by longitudinal dimensions of "hot" zones. 4. Meteor radio communication system, consisting of at least two receiving-transmitting centers (RTC); each one includes a transmitter with transmitting antenna, a receiver with receiving antenna, a modulator, a demodulator, a coder, a decoder, a receiving storage device, a transmitting storage device, the controlling computer, a measuring instrument of radiophysical features of echo signal from meteor trace, characterized in that spiral antennas are used as an antenna. 5.
