Deformation Localization of Reflector Antenna Based on Focal-Field Distribution with CapsNet

An artificial intelligence-assisted reflector antenna deformation localization method based on the focal-field distribution (FFD) feature is presented. Exploring the characteristics of FFD, a capsule network (CapsNet)-based estimation method is used to locate the deformation. The Five-hundred-meter Aperture Spherical radio Telescope (FAST) model is used to verify the effectiveness of the proposed method, and the experimental results confirm that our method can accurately locate the deformation of the reflector antenna.
