METHOD FOR GENERATING ACTUATING COMMAND OF RADIO FUSE Russian patent published in 2016 - IPC F42C13/04 G01S11/10 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition, namely to methods for generating an actuating command of the Doppler radio fuse. Method comprises radiation of sounding radio pulses, reception and amplification of reflected radio pulses, extraction of the signal of the first Doppler frequency F₁, corresponding the target speed, actuation of the Doppler radio fuse when the Doppler signal exceeds the threshold value. Reflected radio pulses are received and amplified in the gate, delayed relative to the gate of sounding radio pulses for the time corresponding to actuating guidance of the radio fuse from the target, signal of the second Doppler frequency F₂ is extracted, the frequency of which is greater than the value of the first Doppler frequency F₁. Adaptation time T is set, during this time the level of amplification of received signals depending on the signal level deviation of the second Doppler frequency F₂ from the threshold value is regulated, maintaining the signal level of the second Doppler frequency F₂ less than the threshold value. After the efflux of adaptation time T, the level of amplification of received signals is recorded, signal level of the first Doppler frequency F₁ is compared with the threshold value, if the threshold value is exceeded, the radio fuse is actuated.

EFFECT: invention allows increasing noise immunity and reducing a probability of false actuating of the radio fuse.
