2D RADAR FOR LOW-ALTITUDE TARGET P-190U

OVERVIEW
  2D Surveillance Radar for low-altitude target detection P-190U implements all of the modern design methods.
  P-190U is a result of the longstanding experience of Ukrainian OEMs in manufacturing up-to-date high-tech equipment for Air Defense, Air Force and Air Traffic Control customers from many countries around the globe. Customers who have P-19 radars that have seen their service life expire can now extend it with this P-190U modernization program.

MAIN FEATURES:
  • full coherence is implemented, due to the significant improvements in radar performance;
  • a wide range of narrow and broadband probing signals enabling radar adaptation to various combat conditions;
  • digital signal processing, including matched filtration, clutter and active jamming suppression, target detection and coordinate measuring, target tracking and data distribution to consumers;
  • practically approved reliable software with user-friendly interface;
  • only COTS components are used from renowned suppliers - this coupled with quality system approval guarantees the high level of reliability.
ADVANTAGES OF P-190U:
  • large number of probing signals, ability to choose the best depending on the air situation, jamming and combat conditions. For instance, narrow band for near field (good detection against clutter background), broadband for long range (large detection range, especially for smaller size targets);
  • parameters of probing signal - working frequency, modulation type, waveform - are all reconfigurable;
  • reconfiguration of signal parameters can be carried out via program or randomly (plus, reconfiguration of probing signal parameters does not affect the quality of clutter suppression);
  • increase of signal to noise ratio due to matched filtration of received signals, increase of detection range and accuracy;
  • significant (up to 100dB) increase of a dynamic range resulting in high jamming immunity and suppression of clutter and weather formations;
  • efficient algorithms for clutter suppression with wind speed compensation;
  • automatic combining of amplitude and coherent channels which decreases signal loss and increases detection range and accuracy;
  • 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);
  • low power consumption;
  • user-friendly design for easy operation (maintenance) of radar;
  • efficient monitoring system of all components.
DEJAMMING CAPABILITIES
A range of hardware and software solutions are implemented in the radar P-190U enabling suppression of the following kinds of jamming:
  • nonsynchronous and chaotic pulse noise;
  • response pulse noise;
  • active noise jamming.
Suppression of pulse noise is implemented in software and enables full suppression of pulse noise.
For suppression of active noise jamming including interfering from TV centres, radios and other sources the following steps are implemented:
  • automatic monitoring of active noise conditions and automatic adaptive working frequency hopping 0.4 MHz discreet;
  • high dynamic range of signal processing system (of the receiver and digital signal processing unit) - 105dB;
  • extra expansion of dynamic range (by 30 dB) through automatic gain control;
  • 4-channel dejammer of active jamming is offered as an option, providing jamming suppression of 32 dB (at SNR of 40 dB).
