Implementation of ZKR-1 Wireless Communication Jammer. Presentation of the Results of Research and Development Projects

The article presents two modular radio transmission jamming devices developed by the consortium of Łukasiewicz-PIAP and ITTI sp. z o.o. as part of the project: „Jamming of radio transmission in selected facilities of the Border Guard”. In typical operating conditions the devices ensure effective blocking of radio communication (prevention of information leakage, protection against remote radio detonation of IED) and analysis of the frequency spectrum in the 25 MHz to 5.9 GHz band. Developed jammers are intended for use by professional state services, have a modern user interface and offer the possibility of remote control. The most important parameters and functionalities are characterized, as well as the distinguishing non-standard operating modes are discussed, i.e. the spectrum analysis mode and the responsive jamming mode, which minimizes the negative effects of user’s exposure to electromagnetic radiation in the vicinity of working devices for a long time.
