Abstract :
Holographic measurements to determine deviations of the 32m Noto antenna with respect to an ideal parabolic surface have been performed at 11.5 GHz. An `ad hoc´ system including a reference secondary antenna was built, and digital beacons coming from commercial TV satellites were used as signal sources. Results clearly showed significant deformations of the dish
