摘　　要：基于地基雷达的月球成像有利于研究地月系统及太阳系演化等科学问题,可以为登陆任务中的着陆区选址提供有力的科学依据,也有助于验证用于深空探测的地基雷达设备的可行性。地基雷达具有穿透性强、全天候、全天时和低成本等优势,国内外已开展一系列基于地基雷达对月球成像的工作,成像方法主要包括时延多普勒方法及干涉成像方法。在不同阶段,采用不同的地基雷达设备和参数,获得了一系列不同分辨率的月球正面图。梳理了国内外地基雷达设备及其参数、成像方法及探测结果等,展望了基于地基雷达设备对月球进行成像的发展趋势。Based on ground-based radar,lunar imaging is beneficial for studying scientific issues such as the Earth-Moon system and the evolution of the solar system,and can provide strong scientific evidence for landing site selection in landing missions.At the same time,it also helps to verify the feasibility of ground-based radar equipment for deep-space exploration.Ground-based radar has advantages such as strong penetration,all-weather,all-time,and low cost.Domestically and internationally,a series of lunar imaging work based on ground-based radar has been carried out.The imaging methods mainly include time-delay Doppler method and interferometric imaging method.At different stages,different ground-based radar equipment and parameters are used to obtain a series of lunar maps with different resolutions.The domestic and foreign ground-based radar equipment and parameters,imaging methods and detection results are reviewed.Finally,the development trend of lunar imaging based on ground-based radar equipment is prospected.
