FIELD: radio engineering.
SUBSTANCE: automatic control method of susceptibility of signal radio receiver with programme tuning of operating frequency (PTOF) consists in the fact that subsequently on each operating frequency in listening watch mode in case of absence of friendly signal there cyclically performed is control of susceptibility of radio receiver, and in mode in which friendly signal is received on each operating frequency according to control programme of operating frequency there set is transfer coefficient of controlled attenuator, which is equal to its value recorded to the memory device when control of susceptibility radio receiver is performed on the appropriate operating frequency.
EFFECT: providing maximum signal-noise ratio on each operating frequency when signals are received from PTOF in the formed interference-noise condition.
