Not sure exactly what type of radar is modeled in game. Currently it goes down to 200ft and out to 12 miles.
As modeled, it looks like the Brit CHAIN HOME system. Looked up some basic stuff on wikipedia...
http://en.wikipedia.org/wiki/Chain_Home"Chain Home had many limitations. With fixed antennas facing the sea, the Observer Corps had to be employed to report aircraft movements once the coast was reached. With detection poor below 5,000 ft (1,500 m), Chain Home Low stations were placed between Chain Home stations to detect aircraft down to 2,000 ft (610 m) but only out to 35 mi (56 km) from the coast, about one-third the range of Chain Home."
Thus two alternatives to the status quo:
A. "Realism." What if we gave "Low station" capability of 12 miles and 2k feet to small/med fields and the standard cape of 35 miles down to 5k feet to large airfields?
I miss the old mix of NOE missions. Given that towns are tougher to take after the town update, they are also a reduced threat. That said, a 2 or 5k bottom to radar detection would probably be too much of a game-changer.
B. "Compromise." What if radar went out 15 miles with coverage extending upward from field elevation +100ft at a 1.5% angle. This would mean that at 12 miles, the radar detection floor would have risen by 900ft above its origin or 1k total.
Thoughts?
