HF radio communication jammer “PURGA”

  • Radio reconnaissance designation of the system:

  • • Automated search, detection, measurement of bearing and coordinates (when operating as matched pair), technical analysis of ground and aerial HF fixed-frequency and frequency- hopping (with up to 300 hops-per-second rate in 10 MHz band) radio emission sources;

  • • Reception and decoding of “Mode-S” identification signals of aerial platforms, displaying trajectories of aerial platforms radiating “Mode-S” signals;

  • • Transfer of radio reconnaissance data to the control post and reception of target designations from the control post (control post is not included in the “Purga” jammer delivery set, its delivery is reasonable in case of availability of four or more jammers).

  • Jamming designation of the system:

  • Radio suppression of ground and aviation HF radio communication links:

  • • Simultaneously up to 4 lines, operating on fixed 1-lettered frequency;

  • • One network, operating in frequency hopping mode having rate of up to 200 hops-per-second in 1-lettered radio transmitter fre- quency, but not more than 10 MHz.
