FIELD: radio engineering.
SUBSTANCE: invention relates to the field of radio engineering and can be used in receiving devices of radio engineering systems. The system of automatic gain control with signal delay for the time of evaluating the power of an additive mixture of signal and interference additionally contains a series-connected high-frequency amplifier, mixer, bandpass filter, splitter, signal delay unit, series-connected intermediate frequency amplifiers (IFA) from the second to the nth, as well as a heterodyne, n analog-to-digital converters, the first and second computing devices, from the second to the 2nth digital-to-analog converters, n electronic keys and n logarithmic amplifiers. The output of the device is the output of the nth IFA.
EFFECT: providing a wide dynamic range while maintaining a high degree of linearity of signal amplification in the main channel in a rapidly changing interference environment.
