RudraM-I

RudraM-I is an anti-radiation missile which can locate and target any radiation-emitting source like enemy radars, communication sites and other Radio Frequency (RF) emitting targets.
It is being developed by Defence Research Development Laboratory (DRDL), Hyderabad, as the nodal agency.
This is the first indigenous anti-radiation missile of the country. It has a range of up to 200 km depending upon the launch conditions.
It can be launched from altitudes of 500 m to 15 km and speeds of 0.6 to 2 mach.
It can play a key role in neutralizing any jamming platforms of the enemy or take out radar stations thereby clearing a path for own fighters to carry out an offensive and also prevent own systems from being jammed.

Anti-radiation missiles are designed to detect, track and neutralize 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.
Once the RudraM missile locks on the target, it is capable of striking accurately even if the radiation source switches off in between.
