摘要：At the time Shanghai Sheshan 25 meter radio telescope was built in 1987, the local radio environment was good. With the increasing interference from the active users of the radio spectrum, the issue of how to protect radio astronomical observations from RFI becomes very serious. This is getting even more demanding with the construction of a new 65 meter in diameter radio telescope at the same region, which will operate in a wide frequency range (from 1.4 GHz to 43 GHz). As the first step, we have performed a RFI monitoring for the site evaluation since 2008. We will report on these assessments along with other related topics of the RFI protection at the Shanghai Sheshan telescope site.
