1L122-1E
Small-sized radar

The 1L122E small-sized radar in 1L122-1E configuration is designed for use as a radar data source for flight radar support at field and temporary airfields and for air defense needs.

Features:

1L122-1Е can be portable or mountable (mobile) on track (wheel) chassis.

Main tasks:

  • detect, position, and track aircraft, cruise missiles, and unmanned aerial vehicles;
  • conduct identification friend-or-foe interrogation;
  • automatically transmit track data to automated control systems.

The design of the small-sized radar ensures:


  • prompt delivery to the points of destination, including those in hard-to-reach and mountainous areas;
  • automatic survey control and orientation relative to North using the GLONASS and GPS satellite navigation systems;
  • automatic operation with minimal crew involvement (automatic target detection, acquisition, and tracking, and automatic data transmission via wire and radio links);
  • long and safe stay of the personnel in the immediate proximity of the radar (transmitters have a low-power ranging signal safe for personnel).
