Lunar Penetrating Radar Data Processing and Analysis Based on CEEMD

2018 17th International Conference on Ground Penetrating Radar (GPR), 2018
Knowledge of the subsurface structure not only provides important information on lunar geology, but also is critical for quantifying potential resources for lunar exploration and engineering for human outposts. The dual-frequency lunar penetrating radar (LPR) aboard the Yutu rover provides a unique opportunity to map subsurface structure to a depth of ...

A Study on Lunar Regolith Quantitative Random Model and Lunar Penetrating Radar Parameter Inversion

IEEE Geoscience and Remote Sensing Letters, 2017
Lunar 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.

Lunar Regolith Penetrating Radar on the Lander for Chang'E-5 Mission

2018 17th International Conference on Ground Penetrating Radar (GPR), 2018
Lunar 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

Echo simulation of lunar penetrating radar: based on a model of inhomogeneous multilayer lunar regolith structure

Research in Astronomy and Astrophysics, 2014
Lunar Penetrating Radar (LPR) based on the time domain Ultra-Wideband (UWB) technique onboard China's Chang'e-3 (CE-3) rover, has the goal of investigating the lunar subsurface structure and detecting the depth of lunar regolith. An inhomogeneous multi-layer microwave transfer inverse-model is established. The dielectric constant of the lunar regolith,

Performance verification of Lunar Regolith Penetrating Array Radar of Chang’E-5 mission

Advances in Space Research, 2019
Abstract 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.
