We already have radar detection in the SoftMAC systems.

If you want to guarantee that no firmware by anyone ever will disable that 
detection inappropriately, the answer is that you can't. All you can do is not 
use that frequency band, even in the places where it's perfectly legal.

Keep in mind, there are only ~50 radars in the US that are the type that this 
interferes with, and you need to be close to the airport to be any problem.

are you looking for a technical solution to a technical problem? or trying to 
find a technical solution for a fear?
