Array Feed To Compensate For Distortion In Antenna
Abstract
System partly restores desired far-field radiation pattern. Adaptive array feed for paraboloidal-reflector antenna helps compensate for effects of slow changes in shape of reflecting surface. Counteracts distortion by illuminating reflector with wave fronts that have "opposite" distortion.
