Embodiment Construction
[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
[0037] The specific implementation of the radio telescope combined with the spherical reflector and the phased array feed (PAF) mainly includes the following aspects:
[0038] Build a spherical reflector. Select a suitable karst depression as the telescope construction site, and carry out necessary earthwork excavation and backfilling. Build the main cable net and the lower cable of the telescope, and adjust the nodes of the cable net to the designed spherical surface. Lay a single-layer spherical reflective panel on the cable net, and make fine adjustments to the main reflective surface.
[0039] Feed support system. Build several towers and feed cabin cable drive systems around the reflective surface. A feed support platform with a two-axis rotation adjustment mechanism developed by the FAST project is used.
[0040] Phased Array Feed (PAF) Design. Acco...
