Jiang Peng, director and chief engineer of the FAST Operation and Development Center, explained that it has taken several years to explore layer by layer from terminal feeders to RF circuit amplifiers to chips. The phase array and 19 beams are currently still imported, and it is hoped that they will be fully localized around 2028. Jiang Peng said that plans are being made to build 64 40-meter radio telescopes around FAST in the future to form a comprehensive aperture array centered on FAST. This is the only comprehensive aperture array in the world centered around a giant telescope and surrounding the construction of a medium aperture telescope. After it is built, it is expected that the resolution of FAST can be increased by 200 times, and the sensitivity can be increased by about 2 times simultaneously.
