摘　　要：人类运用雷达探测技术对月球探测取得了丰硕的科学成果,开展了对月球地形地貌探测、月壤厚度反演、月球次表层结构探测、月球水冰探测等研究。以不同的探测方式和科学目的综述了国内外运用雷达探测技术对月球探测所取得的一系列科学成果,以及我国成功发射"嫦娥三号"卫星,其巡视器"玉兔号"上搭载的测月雷达(Lunar Penetration Radar)将用于探测月球次表层结构和月壤厚度与结构,同时也介绍了测月雷达的基本原理与一些基本指标参数。Fruitful scientific results have been obtained in lunar explorations by using radar techniques. Usages of radars in lunar explorations include probing the lunar topography, inversely deriving data of lunar regolith thickness, probing lunar subsurface structures, and searching for lunar ice/water.In this paper we review some scientific results in domestic and foreign lunar explorations using radars.Our review covers studies of different detection methods and scientific purposes.Recently China successfully launched the‘Chang-E 3’ lunar probe with the Lunar Penetrating Radar （ LPR） as one of its important payloads.The scientific purposes of the LPR are to explore lunar subsurface structures and to measure thickness values and structures of lunar regolith.Our review particularly introduces the working principle and key-parameter values of the LPR.
