| Abstract | 为高效分析与评估台址周边辐射源对天文观测的影响,本文提出一种台址区域化干扰电平阈值量化方法.建立台址地形模型并进行网格划分,采用高效网格检索算法实现台址区域任意位置(网格)至望远镜的相对地形数据提取.在此基础上,选取适应于台址地形特征的电波传播算法,计算台址区域任意位置至望远镜的电波传播损耗,依据望远镜馈源口面干扰电平限值及旁瓣增益,实现台址区域干扰电平阈值量化,并应用于QTT台址,为射电望远镜电磁兼容性设计、台址无线电管理、干扰缓解策略提供重要技术支撑. |
| Other Abstract | To efficiently analyze and evaluate the effect of radiation sources around the station site on astronomical observations, a method to quantify the interference level threshold of station site regionalization is proposed. A terrain model of the station site is established and meshed, and an efficient grid retrieval algorithm is used to extract relative terrain data from any position (grid) within the station site area. Based on this, a radio propagation algorithm adapted to the topographic characteristics of the station site is selected to calculate the radio propagation loss from any location of the station site to the telescope. Considering the interference level limit and side lobe gain of the telescope feed interface, a threshold quantization of the interference level in the station site area is implemented. This approach is then applied to the QTT (QiTai Radio Telescope) station site, providing important technical support for electromagnetic compatibility measurement of the radio telescope, radio management of the station site, and interference mitigation strategy. |
