Explanation :

• On 9th October, 2020, 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.
• Rudram is an air-to-surface missile, designed and developed by the Defence Research and Development Organisation (DRDO).
• It has been developed for the Indian Air Force(IAF’s) requirement to enhance its Suppression of Enemy Air Defence (SEAD) capability.

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.
