Actually, Civil Aviation Radar will not pick up UFO's simply because it is not powerful enough.
All Airliners and almost all other aircraft are required to have a Transponder, which talks to the radar station on the ground. Its called SSR. Although there is a weather radar on Airliners, I have yet to see it show a return for anything other than Weather.
