摘要
表层穿透雷达是一种利用电磁波探测有损介电材料内部结构及材料性能变化的地球物理方法,是目前唯一能够穿透荒芜的行星表面,寻找到隐藏水冰迹象的探测手段,同时也是最适合对行星浅层土壤结构和岩石变化引起的电磁不连续进行成像的无损检测方法。回顾了表层穿透雷达在地外行星探测几十年的发展历史,列出目前国内外采用表层穿透雷达技术的探测任务,总结了这些探测任务所载雷达的科学目标、探测性能及探测成果。在此基础上结合雷达技术发展的最新动态,给出表层穿透雷达在月球与深空探测应用中的主要发展趋势。
Surface Penetrating Radar（SPR）,a kind of geophysical method to survey the internal structure and change of properties of lossy dielectric material by using electromagnetic wave,is only able to penetrate the desolate surface of the planet for finding hidden signs of water ice.In addition,SPR is also the most eligible non-destructive method for imaging planetary shallow layer soil structure and rock changes caused by electromagnetic discontinuous.This paper reviews the decades history of SPR in the application of extraterrestrial planetary exploration,and summarizes the scientific objectives,performance and results of SPRs configured in lunar and deep space missions.Then on this basis,combined with the latest news on radar technology,the main development trend of SPR in lunar and deep space exploration is given.
