P-19 And P-18 Radar Modernization

Fully automatic primary processing of radar data eliminates from the process one of its weakest links - a human-operator - and allows the separation of radar and command post by distance, this significantly increases system survivorship and minimizes the threat of being destroyed by homing missiles.
  • all solid state design;
  • improved combat performance features;
  • improvement of radar maintenance;
  • extension of radar service life;
  • full coherence;
  • cost-efficiency.
The following equipment is installed in a hardware compartment replacing the existing equipment:
  • solid-state transmitter;
  • solid-state receiver;
  • digital signal processing system;
In addition, the following equipment can be supplied at Customer’s request:
  • 4-channel dejammer;
  • height-finder control software and equipment;
  • software for guiding fighter aviation;
  • software for targeting ADS;
  • equipment for documentation.
New possibilities and advantages:
  • significant increase of detection range, accuracy, jamming immunity, numbers of plots and tracks, reliability;
  • significant (up to 100dB) increase of a dynamic range resulting in high jamming immunity and suppression of clutter and weather formations;
  • implemented functions of a radar extractor for post-detection signal processing (detection, location measuring, plots generation, clutter map, scan-to-scan processing, stabilization of false target generation, processing of identification signals, data distribution to consumers);
  • large number of probing signals, ability to choose the best one depending on the air situation, jamming and combat conditions;
  • reconfigurable (via program or randomly) parameters of probing signal - working frequency, modulation type, waveform;
  • efficient algorithms for clutter suppression with wind speed compensation;
  • automatic combining of amplitude and coherent channels that decreases signal loss and increases detection range and accuracy;
  • implementation of automatic built-in diagnostic system.
