FIELD: physics; communication. ^ SUBSTANCE: present invention pertains to communication technology and can be used in radio interferometry with very long baselines, as well as in a universal time and frequencies service. The result is achieved by that, the invention uses standard frequency and time, first and second heterodynes, pseudonoise signal generator, a switch, first and second amplifier of the first intermediate frequency, first and second power amplifiers, a duplexor, a transceiving antenna, first and second clippers, first and second buffer memory, first and second amplifiers of the second intermediate frequency, a device for measuring delays and their derivatives, +90° phase changer, third mixer, 90° phase changer, first, second, third and fourth adders, a multiplier, first and second narrow-band filters, an amplitude detector, switch, first, second and third phase inverters, and first and second band-pass filters. ^ EFFECT: increased noise immunity and accuracy of synchronising remote time scales through suppression of false signals (noise), received on a direct transmission channel and intermodulation channels. ^ 6 dwg |
