Yes. And its much easier than what radars in game are actually capable of.
The F-15s APG-63, and now even the APG-63 PSP and (v)1 are in game. These radars are advanced enough to not just detect these emissions, but classify aircraft just based on these returns, with NCTR. Its why during desert storm only F-15s could do true BVR without AWACS support.
I dont remember PvP giving less than 20-30k for 1 hour. (I earn that in 2 hours now) Regardless, PvP was more engaging than PvE, at least there it wasnt “go to grid E4 - shoot tank - go back to grid D4 - shoot another tank” for 2-3 hours.
