Enemy radar vs SPO Beryoza

[Gloom Demon]

How can I tell whether the enemy, which is painting me with his radar, actually sees me on screen? I mean, the SPO Beryoza, probably, gives warning of radar illumination before the enemy can actually see me right? So how can I tell whether he sees me or not? Is it possible, perhaps, to tell by the circular indicator which tells the emitters power by lighting up notches?

You can't tell this from the Beroyza. A general rule of thumb is to use half strength as being visible, depending on the emitter this can be anywhere between 70 -120+km range.
