A new approach to design an ultra-wideband jammer of radio-controlled explosive devices, in which a multichannel processing unit based on a set of narrowband radio-signal receiving channels with the introduction of noise interference into each channel is replaced by a single-channel microwave-photonics analogue using an optoelectronic radio-signal processor based on an optical recirculation circuit to suppress the channel of the firing code transmission, is proposed and preliminarily investigated. The layout and results of computer simulation for the proposed optoelectronic processor when transmitting standard telecommunication radio signals that confirm the possibility and determine the basic conditions for blocking a radio channel, are highlighted.
