FIELD: radio engineering, communication.
SUBSTANCE: invention relates to radio engineering and can be used in communication systems with pseudorandom operational frequency readjustment. One device combines functions of filtering pseudorandom operational frequency readjustment (PROFR) signals, delay search and demodulation of PROFR signals and uses, during delay search, information PROFR signals having an identical form. The device includes an analogue-to-digital converter, a "window" signal processing unit, a fast Fourier transform unit, a PROFR demodulator, a signal weighted summation unit, a hypothesis selection unit, a control unit, a hypothesis selector, a PPS reference generator and a PSP generator.
EFFECT: shorter signal delay search, high radio security and noise-immunity of the radio line.
