A story of regolith told by Lunar Penetrating Radar
Icarus, 2019Abstract Knowledge of the lunar regolith not only provides important information about lunar geology, but is also critical to quantifying potential resources for lunar exploration and engineering for human outposts. The Lunar Penetrating Radar (LPR) onboard China's Chang'E-3 (CE-3) provides a unique opportunity for mapping the subsurface structure ...

The Design of Payload Lunar Regolith Penetrating Radar on Chang'E-5 Lander
IEEE Aerospace and Electronic Systems Magazine, 2021Sampling return in Chang'E-5 (CE-5) mission is the third phase of three strategic steps of China's lunar program. The three strategic steps are orbiting, landing, and returning. The sampling and drilling device is mounted on the Lander. One task of the CE-5 Lunar Regolith Penetrating Radar (LRPR) is to provide information support for the drilling and ...

A Study on Lunar Regolith Quantitative Random Model and Lunar Penetrating Radar Parameter Inversion
IEEE Geoscience and Remote Sensing Letters, 2017Lunar penetrating radar (LPR) is an important way to evaluate the geological structure of the subsurface of the moon. The Chang’E-3 has utilized LPR, which is equipped on the lunar rover named Yutu, to obtain the shallow lunar regolith structure in Mare Imbrium.

Journal of Geophysical Research: Planets, 2021
AbstractIt is generally believed that the top centimeters of mature lunar regolith should be dominated by fine particles that contain few rocky fragments, but surface fragments are occasionally visible in mature lunar regolith. Based on amplitudes of surface echoes received by the Lunar Penetrating Radar onboard the Yutu‐2 rover of the Chang'E‐4 ...

Lunar Regolith Penetrating Radar on the Lander for Chang'E-5 Mission
2018 17th International Conference on Ground Penetrating Radar (GPR), 2018Lunar Regolith Penetrating Radar (LRPR) is one payload of Lander for Chang'E-5. LRPR's scientific missions are: (1) providing information support for drill and sampling device; (2) sounding lunar regolith thickness and structure below the Lander area, which is covered by radar's antenna. In order to obtain detection data effectively, it is necessary to

Performance verification of Lunar Regolith Penetrating Array Radar of Chang’E-5 mission
Advances in Space Research, 2019Abstract Lunar Regolith Penetrating Array Radar (LRPR) is one main payload of the Lander for Chinese Chang’E-5 (CE-5) mission. It is used to support the drilling and sampling device and to detect lunar regolith thickness and structure of the landing site. LRPR will only work in situ under static status, so the antenna array is employed.
