“ROSA-RB” LOW-FLYING TARGET DETECTION RADAR SYSTEM

Designation: automatic detection and tracking of low-altitude air objects and transmission of track data to an automated control system.

Composition:

  • 1 to 5 autonomous low-altitude target detection radars;
  • remote control system.
Main element of low-flying target detection radar is a 16-channel transmitterreceiver integrated with antenna.

Advantages:

  • effective detection of an air object with small RCS at extreme low altitudes;
  • operator-free automatic operation;
  • high radar concealment and jamming immunity;
  • fully automatic functional check;
  • continuous operation for not less than 1 month.
