FIELD: radio navigation, radar, and digital data transfer systems. SUBSTANCE: device that may be used, for example, in digital data transfer systems using noise-like signals basing on pseudorandom phase (O, π) modulated sequences and may be found useful for reducing signal retrieval time in the course of putting in synchronism provides for reducing look-up time of desired area to retrieve frequency and time parameters of signal. It has signal delay meter incorporating detector, two multipliers, two reset integrators, harmonic- wave oscillator, divider, and computing device implementing y=atn(x) function. Signal delay meter functions to measure incoming signal delay to eliminate signal delay retrieval area from total area of frequency and time parameters which makes it possible to reduce look-up time of entire retrieval area by Mr times (by base times). EFFECT: reduced retrieval time. 1 cl, 2 dwg
