Podberyozovik-ET1 Shipborne Radar is designed for detection of air (including small-sized and flying at low altitude) and surface targets. The radar performs the following tasks:

  • „friend-or-foe identification of targets, output of primary radar data to firing units, EW means and data processing system;
  • tracking of detected targets integrating utilization of data processing systems and output of secondary radar data to fire control systems.

Podberyozovik-ET1 Radar has been manufactured since 1982 and is being constantly modernized (last modernization was performed in 2005).

Podberyozovik-ET1 Radar high performance and jam-resistance is ensured by:

  • adaptive energy distribution in space;
  • „broadband electronic frequency tuning;
  • „high spatial resolution and low level of antenna radiation pattern side lobes;
  • complex signals with high level of resolution;
  • „non-linear methods of signal processing;
  • „logical post-detection signal processing;
  • „two-phase moving target indication with variation of signal repetition frequency.
