摘　　要：非相干散射雷达是目前地面监测电离层最强大的设备,在月球等天体目标探测方面也具有潜在价值。本文介绍了曲靖非相干散射雷达技术特点与月球探测数据处理方法,分析了月球探测初步结果以及目前存在的不足与下一步工作计划。结果表明,曲靖非相干散射雷达目前可探测月球单极化回波(右旋圆极化)、反演月表反射系数和粗糙度、进行初步成像等,探测结果与现有研究结果基本一致。本文工作对我国地基雷达天文探测具有重要意义。Incoherent scatter radar is the most powerful tool to measure the ionosphere on the ground and also has the potential for detection of the astronomical objects such as the moon.This paper introduces the technical characteristics of Qujing incoherent scatter radar and its data processing method for the lunar observation.The preliminary measurement data are analyzed.Both the existing problems and shortcomings are given,and the plan in the future are also presented.The results show that Qujing incoherent scatter radar can detect lunar radar echo(right circular polarization),inverse the lunar reflection coefficients and roughness,and also image the lunar near side.Our results are in good agreement with earlier work done by others.Our work is of values for the ground-based radar astronomy measurement.
