摘要

摘要: 测月雷达是嫦娥三号月球巡视器搭载的重要科学载荷之一, 用以实现月表之下100 m之内的穿透成像。该文介绍了测月雷达的系统组成与工作原理, 对获取到的月球科学数据进行了详细分析。在此基础上研究了有针对性的数据处理方法, 并给出第1通道数据的初步处理结果。从处理结果中可知, 测月雷达有效信号深度达到100m以上, 在大约40 m深处有雷达反射异常, 初步分析为嫦娥三号着陆区月表之下两套地层的分界线。

Abstract: Lunar Penetrating Radar (LPR), which is one of the most important science payloads onboard the Chang'E-3 (CE-3) rover, is used to obtain electromagnetic image less than 100 m beneath the lunar surface. This paper describes the system composition and working mechanism of the LPR and presents a detailed analysis of its data. We investigated special signal-processing methods and present the result of channel-1 data. The result shows that the effective echo occurs at depths greater than 100 m. Moreover, an unusual reflection exists at depth of 40 m, which may be the boundary of two geological units beneath the lunar surface.
