Square Kilometre Array (SKA) Radio Telescope Antenna, the largest physical contribution contract signed to date by the SKA International Organization.
Building upon the testing and validation of the initial two prototype units, performance enhancements and structural upgrades were implemented. Digital analysis of the surface shape accuracy adjustments was conducted, addressing the electrical performance across the full pitch range. An innovative method was introduced involving panel adjustment threshold bias to achieve repeatability in reflector surface shape adjustments, thereby enhancing the overall electrical performance of the antenna. Leveraging structural strain energy distribution and mode analysis, weak points were identified and targeted improvements were made, resulting in an antenna resonance frequency increase to 2.5Hz.
