Radio environment degrades significantly at Nan Shan 26 m Radio Telescope（NSRT） base due to new and upgraded electrical devices on-site and more establishment of surrounding radio communication services. How do we mitigate them effectively? Firstly, a quasi-real time Radio Frequency Interference（RFI） measurement method is employed for RFI detection and spectral analysis based on the layout for potential on-site interference areas and off-site radio communication services. Our investigation at th...
