Distortion compensation techniques for large reflector antennas

The high-frequency limit of reflector antennas is usually governed by the magnitude of the surface error. Whereas little can be done for the high-spatial frequency portion of this error, there are various techniques that can be employed to compensate for large-scale surface errors due to gravity induced distortions for spacecraft antennas.

A Method Using Focal Plane Analysis to Determine the Performance of Reflector Antennas

Reflector antenna optimization schemes using array feeds and deformable flat plates (DFP) have been used to design systems that recover antenna losses resulting from antenna distortions.
