RAJENDRA RADAR

RAJENDRA RADAR

  • Rajendra is passive phased array radar developed by the Defence Research and Development Organisation. It is multifunction radar, capable of surveillance, tracking and engaging low radar cross section targets. It is the heart of the Akash surface-to-air missile system and is the primary fire control sensor for an Akash battery.
  • The Rajendra Multi-Function Phased Array radar system, designed at the Electronics and Radar Development Establishment (LRDE), part of DRDO, is currently in production at Bharat Electronics Limited, Ghaziabad. It is named after India’s First president Dr. Rajendra Prasad.
  • Rajendra is a slewable passive phased array radar used for 3-D target detection, multi target tracking and multiple missile guidance under extreme hostile EW environment.
  • It makes use of a passive phased array to search a volume of space, distinguish between hostile and friendly targets, automatically track up to 64 targets and command one of several launchers to engage up to 4 targets simultaneously.
  • Initially designed as a standalone system, Rajendra is now equipped with the ability to integrate with a network of sensors, including long and medium-range surveillance radars of foreign and indigenous origin.
  • Rajendra radar uses phase shifters integrated in large numbers for electronic beam steering. This allows Rajendra radar to simultaneously track multiple aircraft and also guide multiple missiles towards these targets.
  • The phased array radar rotates 360 degrees on a rotating turnstile at a moderate speed. This allows it to perform 360 degree surveillance.

The major functions of the Rajendra are:

  • Surveillance of the assigned volume of space
  • Acquisition of aircraft targets either independently or handed over from group control centre via the 3-D CAR or from the battery surveillance radar
  • Tracking of targets
  • Tracking of assigned targets (up to 4) and missiles (up to 8) during engagement
  • Command guidance of missiles (up. to 8)
  • Integrated IFF (Identification Friend or Foe) functions
