摘要：射电望远镜的系统组成包括用于搜集射电波的天线模块、用于扩大电参量的高敏接受模块、分析模块以及显示模块等多个部分。结合我国现有射电天文望远镜基本情况，覆盖毫米波频段的射电望远镜不多，故与FOD探测雷达的同频兼容的也不多。文章以某天文台射电望远镜为例，分析其与FOD探测雷达的频率兼容性。

Abstract： The system composition of radio telescope includes： the composition of this equipment contains several parts such as antenna module for collecting radio waves， high-sensitivity receiver module for expanding electrical parameters， analysis module， and display module. Combined with the basic situation of existing radio astronomical telescopes in China， there are not many radio telescopes covering the millimeter wave band， so there are not many compatible with the same frequency of FOD detection radar. This paper takes an observatory radio telescope as an example and analyzes its frequency compatibility with FOD detection radar

Key words： FOD; astronomy; compatibility; interference
