the way I understand EW is that its purpose is to deny the radar accurate ranging information. The missile will still track you because the radar has locked on to you, because you were flying very contrasted to the background, or you were a blip getting bigger and reflecting more rays relative to the flashlight (radar). When a missile is not budging, your EW suite is useless. Because the radar has burned through your bluff. Because you were close.
If you read the hunter killers (Dan Hampton), you would know they had dedicated panels to discern signals and their level of an emitter. The launching platform would usually loft the missile to gain maximum range while also making themselves more vulnerable in pulling up.
WRT your question, I dont think ther is any difference. Caveat: I am not a pilot, nor ever been involved with the military service. Its my personal opinion. I could be wrong.
