«Rosa» low-flying target detection radar system

  • LARS  «Rosa»

  • Creation of a continuous low-altitude radar field along the assigned borderline

  • Automated workstation indicator at system remote control post


«Rosa» is designed for automatic detection and tracking of low-altitude aerial platforms and output of track information to an automated control system.

  • from 1 to 5 autonomous low-altitude target detection radar sets (LARS);
  • remote control system;
  • SPTA set.

  • absence of moving parts due to use of a ring-shaped solid-state phased array;
  • use of digital synthesis of the probing signal and digital processing of the received signal;
  • effective detection of low-flying small-RCS aerial platforms;
  • operator-free automatic operation;
  • fully automatic functional check;
  • high radar concealment and jamming immunity.
Manufacturer’s technical support and SPTA supply outside the warranty period are provided throughout the system service life under separate agreements.
