METHOD OF PROTECTING THE RADIOFUSE ON THE BASIS OF AUTODYNE FROM RADIO INTERFERENCE Russian patent published in 2018 - IPC F42C13/00 H04B15/00 

FIELD: blasting operations.

SUBSTANCE: invention relates to non-contact fuses and can be used to increase the noise immunity of radio fuses from the effects of various interference. Proposed method for protecting the radio detonator based on autodyne from radio interference is as follows. During the operation of a radio fuse based on autodyne autodyne on the radiation is switched on for a certain period of time, and for reception of autodyne it works continuously, and the moments of switching on and off the operation of the autodyne for radiation are carried out randomly. With this scheme of operation of the autodyne station, the radio interference producer can not repeat the sending of radio signals in sequence, in the duration of the radiation, in the radiation frequency, in the modulation scheme of the radiation frequency, which is identical to that of the autodyne. Mismatch of the parameters during the operation of the autodyne for reception will be the criterion for the operation of the interference station in the area of the detonator and the signal for transferring the radio detonator to the contact detonation mode.

EFFECT: invention allows reliable operation of the fuse.
