METHOD OF CLOCK SYNCHRONIZATION AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G04C11/00 

FIELD: physics.

SUBSTANCE: device for the clock synchronization realizing the proposed method, comprises a standard 1 of frequency and time, local oscillators 2.1, 2.2, a dither signal generator 3, a switch 4, mixers 5, 13, 19, 28 and 30, an amplifier of the first intermediate frequency, and power amplifiers7 and 12, a duplexer 8, a transceiving antenna 9, clippers 10 and 15, buffer memories 11 and 16, amplifiers 14 and 20 of the second intermediate frequency, a meter 17 of the delays and their derivatives, phase shifters 18 and 21 at 90°, adders 22, 41, 44 and 48, multipliers 23 and 34, narrow-band filters 24 and 39, an amplitude detector 25, a key 26, a reference frequency block 27, an amplifier 29 of the third intermediate frequency, low frequency filters 31 and 35, a meter 32 of Doppler frequencies, a correlator 33, an extreme knob 36, a variable delay block 37, a range indicator 38, phase inverters 40, 43 and 46.

EFFECT: increasing the noise immunity and the synchronization accuracy of the remote time scales by suppressing false signals received on the direct transmission channel and on the intermodulation channels.
