    Pre-research for Large Radio Telescope(Fast)--"Active main spherical reflector"
    Update time: 2009-09-02
    Text Size: A A A

     The subject is part of pre-research project for “FAST”。New concept for active main spherical reflector of Large Radio Telescope will be realized through research for structure of active main spherical reflector,supporting system and control system。Namely,the illuminated part of the main spherical reflector by feed is to be adjustable continuously to fit a paraboloid of revolution in real time。

      The scaled model with ratio of 1:3 for the subject has been finished。
