Study on regolith modeling and lunar penetrating radar simulation
2016 16th International Conference on Ground Penetrating Radar (GPR), 2016Lunar penetrating radar (LPR) is an important way to carry out lunar probing. The detection result of Rabbit lunar radar carried by Chang'E 3 provides a reliable scientific foundation for studying the underground structure and depth distribution of the moon.

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 ...

Inflatable impulse radiating antenna for lunar penetrating radar
2017 9th International Workshop on Advanced Ground Penetrating Radar (IWAGPR), 2017In this paper, an inflatable impulse radiating antenna (inf-IRA) that can be used in lunar penetrating radar application is described. The inf-IRA is covered by thin films as a main material so that it can be inflated as the air is injected and be packaged small size as the air is deflated.

The penetrating depth analysis of Lunar Penetrating Radar onboard Chang’e-3 rover
Research in Astronomy and Astrophysics, 2017Lunar Penetrating Radar (LPR) has successfully been used to acquire a large amount of scientific data during its in-situ detection. The analysis of penetrating depth can help to determine whether the target is within the effective detection range and contribute to distinguishing useful echoes from noise.

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

Abstract It 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 lunar penetrating radar (LPR) carried on the Chang E-3 Yutu Rover observations at 500 MHz successfully reveals the thickness and geological structure of the shallow lunar regolith. Previous work used the calculated permittivity and the migration image to estimate the layer interface and local target.
