Abstract EN
With the development of radio telescope antennas with large apertures, high gain, and wide frequency bands, compensation methods, such as mechanical or electronic compensation, are obviously essential to ensure the electrical performance of antennas that work in complex environments.
Since traditional compensation methods can only adjust antenna pointing but not the surface accuracy, which are limited for obtaining high surface precision and aperture efficiency, active surface adjustment has become an indispensable tool in this field.
Therefore, the development process of electrical performance compensation methods for radio telescope antennas is introduced.
Further, a series of analyses of the five key technologies of active surface adjustment is presented.
Then, four typical large antennas that have been designed with active main reflector technology are presented and compared.
Finally, future research directions and suggestions for reflector antenna compensation methods based on active surface adjustment are presented.
