HomeOur ProductsS-band primary surveillance radar with monopulse mode S secondary surveillance radar

PURPOSE

The new generation airfield radar has advanced capabilities of detection of aircraft position in terminal areas and provides conditions for transition to reduced separation rules in terminal areas with the aim of capacity improvement of the aerodromes.

KEY FEATURES

Hardware

  • Use of up-to-date electronic components and engineering solutions allows to place all the hardware of primary and secondary channels in one standard cabinet;
  • Minimization of the dimensions of the hardware allows, in turn, to increase the reliability of the radar and to place all the hardware in one shelter, and to install the shelter itself directly on the mast.

Antenna of the primary channel

  • emitter-polarizer is placed outside the beam, which allows to increase the gain and reduce the side-lobe level;
  • integrated dipole of the test generator that allows to test the whole processing path, including the antenna.

Drive string

  • in the drive string, control signals to an antenna and status signals from the antenna are transmitted in a noncontact manner, that is why there are no slip rings in the string, the sliding contacts of which often lead to failures of radars;
  • position sensors of the antenna are directly connected to the antenna; such transmission does not have backlash and kinematic errors, which allows high-accuracy measurement of rotation angle of the antenna.

COMPOSITION OF THE RADAR

  • primary surveillance radar (PSR) hardware (consists of PSR transceivers, PSR amplifiers, a PSR switch, PSR data processing hardware);
  • PSR antenna;
  • HF path of PSR.
  • drive string;
  • drive string control hardware;
  • monopulse secondary radar (MSSR) (consists of SSR transceivers, SSR amplifiers, an SSR switch, an SSR data processing device);
  • SSR antenna;
  • HF path of SSR;
  • SSR test transponder (consists of a test transponder unit and a test transponder antenna);
  • remote control equipment (RCE) (consists of an RCE cabinet, an information bar and a mobile automated working position);
  • mast (height from 3 to 35 m);
  • shelter with a life support system and uninterrupted power supply.
