自2007年以来，中国已成功进行了五次月球探测任务。这些任务标志着中国成功实施了“绕月、着陆、返回”三步走探月计划。其中，“嫦娥四号”任务中的“玉兔二号”月球车携带的探月雷达（LPR）是目前唯一仍在月球背面工作的雷达。迄今为止，“玉兔二号”雷达已测量了大量的科学数据，其观测结果对人类认识月球表面地质演化和勘探可能的月球原位资源具有重要意义。本文综述了前人基于玉兔二号雷达探测数据取得的科学成果，主要从CE-4着陆点浅层地质构造、浅层地下物质介电特性和特殊地质特征三个方面进行了综述。最后，展望了“玉兔二号”雷达的研究重点和未来探索方向，以及探地雷达的应用趋势。
China has successfully carried out five lunar exploration missions since 2007. These missions indicate that China has successfully implemented a three-step lunar exploration program of “orbiting, landing, and returning”. Among them, the Lunar Penetrating Radar (LPR) carried by the Yutu-2 rover in the Chang’E-4 (CE-4) mission is the only one still operating on the far side of the Moon. Up to now, the Yutu-2 radar has measured a large amount of scientific data, and its observations are of great significance to human cognition of the geological evolution of the lunar surface and the exploration of possible lunar in situ resources. This paper reviews the scientific results obtained by previous researchers based on the radar exploration data of Yutu-2, focusing mainly on three aspects, e.g., the geological structure of the shallow surface at the CE-4 landing site, the dielectric properties of the shallow subsurface materials and the special geological features. Finally, the prospects of Yutu-2 radar research priorities and future exploration, and the application trend of Moon-based ground-penetrating radar are given.
