Radiation homing

The other main aspect of ECCM, is to program sensors or seekers to detect attempts at ECM and possible even to take advantage of it. For example, some modern fire-and-forget missiles like the Vympel R-77 and the AMRAAM are able to home in directly on sources of radar jamming if the jamming is too powerful to allow them to find and track the target normally. This mode, called 'home-on-jam', actually makes the missile's job easier. Some missile seekers actually target the enemy's radiation sources, and are therefore called "anti-radiation missiles" (ARM). The jamming in this case effectively becomes a beacon announcing the presence and location of the transmitter. This makes the use of such ECM a difficult decision; it may serve to obscure an exact location from a non-ARM missile, but in doing so it must put the jamming vehicle at risk of being targeted and hit by ARMs.

Why did you post two threads?

Because this isn't the same as the other thread.
