| 英文摘要 | The radio environment of the radio astronomical telescope site is determined by the surrounding interference sources, their geographical location, propagation environment, and other comprehensive factors. Therefore, the location and geographical distribution characteristics of interference sources in the 5-10km radio protection coordination zone are crucial for the observation performance of the radio astronomical telescope. This article proposes a method for comprehensive analysis of the radio environment at radio astronomical telescope sites using electromagnetic propagation analysis software. Information such as interference signal source location, transmission power, and signal source direction map are collected and loaded into a high-precision map. The signal reception power intensity of the required site in the interference signal source frequency band is obtained through the electromagnetic propagation analysis software HTZ communications. Based on the above method, the key parameters of the 800MHz telecommunications base station within 10km around the Jingdong Radio Telescope (JRT) site with a transmission frequency of 800MHz were obtained. The terrain propagation model fusion analysis was carried out on the 800MHz interference situation of the radio telescope site. Finally, the comprehensive interference of the area to the Jingdong Radio Observatory site was calculated to be-55.30dBm, providing a basis and observation method for the interference situation of radio astronomy observation in the Jingdong area. © 2025 IEEE. |
