> First of all, there's no guarantee that you will be able to use BVR. A stealth fighter using its radar is the same as a man in a camouflage at night turning on his search light. Everybody will know where you are.

This is simply not true for modern AESA radars. It's only true for radars built with an 80's technology level. Modern radars are capable of producing search beams so narrow that they cannot be reliably used for locating the source. When someone is using a LPI radar near you, you can tell that someone has a radar on, but you will only have a very vague idea of the direction they are in, and no idea at all of how far away they are. And since other planes near you (or even other detectors on your own plane) do not get to see the same beam, only the next one that comes after a random interval, you cannot use multiple detectors for deducing the origin of the beam.

The fact that this myth of radars telling everyone where your are is so persistent is annoying, but also somewhat useful. Simply because if someone repeats it, it tells everyone that they have not updated their ideas about how air combat works since the cold war ended and they should be ignored.
