An EMC control method for large-diameter radio telescope
Abstract
<p indent="0mm">The large-diameter radio telescope has extremely high system sensitivity; however, various electronic devices will be equipped at the constructing and operating process, which will generate electromagnetic interference impacting on radio astronomical observations. Therefore, it is necessary to investigate effective Electromagnetic Compatibility (EMC) control approach. This paper based the EMC requirements of radio astronomy, analyzing the deficiencies and adaptability of the EMC evaluation standards available, considering the feasibility of engineering process and operating management as well, on which an EMC control method for large-diameter radio telescope was proposed, including quantified interference level limits for the electronic equipment, EMC measurement method and shielding effectiveness testing method. This method will be applied to the proposed steerable 110-m aperture radio telescope (Qi Tai Radio Telescope, QTT) in Xinjiang, ensuring that QTT has good EMC performance.</p>
