“GROZA” UHF/VHF radio communication jammer

  • Radio reconnaissance designation:

  • • Automatic search, detection, direction finding and determination of coordinates (when operating as coupled pair), technical analysis of emissions of UHF ground and aerial radio communication means operating at fixed frequencies and in frequency-hopping mode (with up to 1000 hops-per-second rate in 30 MHz band);

  • • Receipt and transmission of information to the control post.

  • Jamming designation:

  • Radio suppression of ground, aerial and satellite UHF radio communi¬cation links:

  • • Up to 20 fixed-frequency links quasi-simultaneously;

  • • One frequency-hopping link with up to 1 000 hops-per-second rate in 30 MHz band.
