Anti-Radiation Missile

India’s first indigenous anti-radiation missile, Rudram, developed for the Indian Air Force, was successfully flight-tested from a Sukhoi-30 MKI jet off the east coast recently.

 

What is an anti-radiation missile?

  • Anti-radiation missiles are designed to detect, track and neutralise the adversary’s radar, communication assets and other radio frequency sources, which are generally part of their air defence systems.
  • Such a missile’s navigation mechanism comprises an inertial navigation system — a computerised mechanism that uses changes in the object’s own position — coupled with GPS, which is satellite-based.
  • For guidance, it has a “passive homing head” — a system that can detect, classify and engage targets (radio frequency sources in this case) over a wide band of frequencies as programmed.
  • Officials said once the Rudram missile locks on the target, it is capable of striking accurately even if the radiation source switches off in between. Officials said the missile has an operational range of more than 100 km, based on the launch parameters from the fighter jet.

 

Significance 

  • Rudram has been developed for the IAF’s requirement to enhance its Suppression of Enemy Air Defence (SEAD) capability.
  • As one of the many aspects of SEAD tactics, anti-radiation missiles are used mainly in the initial part of air conflict to strike at the air defence assets of the enemy, and also in later parts, leading to higher survivability to a country’s own aircraft.
  • Neutralising or disrupting the operations of the adversary’s early warning radars, command and control systems, surveillance systems that use radio frequencies and give inputs for anti-aircraft weaponry, can be very crucial.
  • Scientists said modern-day warfare is more and more network-centric, which means it comprises elaborate detection, surveillance and communication systems that are integrated with the weapons systems.
