Well, I dont think the Mirage radar is in shit shape, neglected or game breaking bugged, except the narrow scan width bug - but that is not game breaking, just slightly annoying.
But do correct me if Im wrong, regarding a doppler radar, a relative small one at that. Its an incredibly dynamic enviroment, and doppler radars do not like being notched, nor are they very capeable in a rear aspect chase, when their speed is +/- 100 kts of the target. Add to that height aspect, if target is below you.
The massive and very powerful AWG-9 in the Tomcat is loosing lock left right and center, even in very close - I guess that is a game breaker too then? That goes for the Hornet too.
I just have this feeling that many people expect radars to be these all seeing all powerful devices, that once locked on, will not loose lock again, expect in a very narrow notch window. I think real world is the exact opposite, and that the Razbam Mirage radar is doing a great job imitating all those limitations, but thats just me.
