Abstract	射电望远镜具有极高的灵敏度和很宽的工作频率范围,在执行观测任务时,不仅会接收到观测目标产生的信号,还会接收到台址内外各类电磁干扰信号,从而影响观测的准确性,其中以通信基站的干扰最为突出.为了预测通信基站对射电望远镜的电磁干扰,本文提出了一种基于相对地形的电磁干扰预测方法.该方法将地形高程数据转换成相对地形数据,以相对地形的波动高度作为判据,采用Deygout模型计算了通信基站到射电望远镜的路径损耗.再结合通信基站的天线参数,最终得到了通信基站对射电望远镜的干扰功率.文中着重分析了该方法的实现过程,为下一步自主研发射电望远镜电磁干扰预测软件提供了基础.
Other Abstract	Radio telescopes have extremely high sensitivity and wide operating frequency range. When performing observation tasks, they will not only receive the signals generated by the observed targets, but also receive electromagnetic interference signals inside and outside the radio telescope site. These interference signals, especially the interference from communication base stations, will affect the accuracy of the observation. In order to predict the electromagnetic interference of the communication base station to the radio telescope, an electromagnetic interference prediction method based on relative terrain is proposed. This method converts the terrain elevation data into relative terrain data, taking the relative height of terrain as the criterion, and calculates the path loss of the communication base station to the radio telescope by using Deygout model. Then, combined with the parameters of the base station antenna, the interference power of the communication base station to the radio telescope is obtained. This paper focuses on the analytical process of the proposed method, which provides a good foundation for developing the electromagnetic interference prediction software of radio telescope.
