METHOD FOR GENERATING SIGNAL IN MODE OF PROGRAMMED OPERATIONAL FREQUENCY READJUSTMENT WITH VARIABLE FREQUENCY BAND Russian patent published in 2021 - IPC H04B1/713 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and is intended for use in radio communication systems with programmed operational frequency readjustment (POFR) using structurally secretive radio signals. In the method of generating a signal in the mode of programmed operational frequency readjustment with a variable frequency band as well, the primary signal is modulated with a digital sequence extended with Barker codes of different widths, the choice of which is carried out in accordance with the given first pseudo-random code digital sequence (PCDS). Then the received signal is multiplied with the reference oscillations the frequencies of which change in accordance with the second PCDS. Then the generated signal is transmitted to the receiving side. In this case, the synchronous selection of the frequency number and the Barker code number is carried out in accordance with the first and second PCDS.

EFFECT: increasing the structural secrecy of transmission in the mode with POFR.
