摘　　要：针对月背低频射电探测阵列建设问题开展了任务需求分析,给出了未来开展宇宙黑暗时代探测所需的流量密度极限及探测阵列规模,在此基础上提出了月背低频射电探测阵列基本型的初步方案设想.探测阵列基本型为一个最大基线长度10 km的阵列,由一个基站和20个子站构成,每个子站带有12个天线节点,分析了阵列建设所需的关键技术,重点论述了系统组成、站址选择、天线设计和适应月夜工作的能源系统设计及天线部署、阵列建造对月表原位建造的需求,为月背大规模射电探测阵列的建造提供参考.In view of the construction of large-scale array for radio astromomy on the farside(LARAF)of the Moon,the task requirement analysis was carried out,the limit of flux density and scale of the array required for future cosmic dark age detection were given,and the preliminary scheme of the basic type of LARAF was proposed.The basic type of LARAF has a master station and 20 sub-stations,each sub-station has 12 antenna units,and the maximum baseline is about 10 km.The key technologies required for this mission were analyzed.This paper focuses on the system composition,site selection,antenna design and energy system design for moonlit work,as well as the requirements of antenna deployment and array construction for in-situ construction of lunar surface,which provides reference for the construction of large-scale radio detection array on the back of the moon.
