First off - I'm definitely not an expert on this stuff. But first, some Qs of my own.
ARM? Anti Radiation Missile? Does that mean A-G or A-A?
Reason I ask is - that looks like an A-A display. Something generated by the big sensor up front - the radar. You called it - you said a b-scope. I agree.
HTS is A-G and is fed by a sensor other than the radar. Its not a b-scope - its more of the "God's eye" variety.
I don't think the two are in the same class, for that reason.
How sure are you that the vertical scale is distance? (I don't read Russian.)
Could it be something else? Like frequency? Actually, I doubt it, but I've atleast got to ask.
Because it is a b-scope, can we assume its for A-A? And if its A-A, does this mode indicate the emissions associated with oncoming A-A contacts?
Just pure speculation here - I've never seen this stuff before in my life.
What do y'all think?
