What is an anti-radiation missile (ARM)?

Which missiles have home-on-jam capability?

  • Several surface-to-surface missiles, like the P-700 Granit, P-500 Bazalt, MM40 Exocet, B611MR, and Otomat, include a home-on-jam capability wherein the receiver component of their active radar homing is used to home in on enemy radar, ECM or communications.

Why do missiles fly faster when the radar is off?

  • This allows them to remember the radar's direction if it is turned off and continue to fly towards it. ARMs are less likely to hit the radar if the radar is turned off shortly after the missile is launched, as the longer the radar is off (and assuming it never turns back on), the more error is introduced into the missile's course.

What are the advantages of missile guidance systems?

  • Such missiles have several advantages over other missile guidance techniques: they do not trigger radar warning receivers (conferring a measure of surprise) and they can have a longer range. In the 1970s, Hughes Aerospace had a project called BRAZO (Spanish for ARM).
