Phase Analysis of Aperture Surface on Ring Focus Antenna
The ring focus antenna has special electromagnetic characteristics and application fields. The phase error of ring focus antenna is analyzed theoretically and simulatedly. The phase error caused by the position deviation of the feed and the subreflector, the compensation relationship between the main reflector and subreflector, and the optical path difference caused by the operation of the antenna in holographic measurement are derived. The results will provide theoretical basis and reference for accurate surface measurement and compensation of the ring focus antenna.
期刊介绍:
The vigorous growth of astronomical and astrophysical science in China led to an increase in papers on astrophysics which Acta Astronomica Sinica could no longer absorb. Translations of papers from two new journals the Chinese Journal of Space Science and Acta Astrophysica Sinica are added to the translation of Acta Astronomica Sinica to form the new journal Chinese Astronomy and Astrophysics. Chinese Astronomy and Astrophysics brings English translations of notable articles to astronomers and astrophysicists outside China.
