Method and system for detecting thickness of lunar soil and subsurface geological structure of moon

Abstract

The invention discloses a method and system for detecting the thickness of lunar soil and the subsurface geological structure of the moon via an ultra-wide-band carrier-free pulse radar. A radar system includes two detection channels, wherein the first channel work at an HF / VHF waveband in a one-transmission-one-reception mode, and is used for detecting the geological structure of rocks at the subsurface of the moon; and the second channel works at a UHF waveband in a one-transmission-two-reception mode, and can accurately detect the thickness of the lunar soil layer. The ultra-wide-band carrier-free pulse radar is mounted on a moon rover and moves with the moon rover, and the two detection channels work alternatively, and respectively radiate and receive ultra-wide-band carrier-free pulses to complete detection for the thickness distribution of the lunar soil and the geologic structure of the rocks at the subsurface of the moon. Detected data is transmitted back to the earth, and the geologic structure of the rocks at the subsurface of the moon and the structure of the lunar soil layer are drawn on a display screen after processes as data filter and amplification.

Description

technical field [0001] The invention belongs to the technical field of lunar geological structure detection, in particular to a method and system for detecting lunar soil thickness and lunar subsurface geological structure by using an ultra-wideband non-carrier pulse radar. Background technique [0002] At present, human beings still know little about the geological structure inside the moon and the distribution of lunar soil thickness. The known geological structure information in the depth range of 1-2km in some areas of the moon mainly comes from the detection results of the US Apollo program. In 1973, the Apollo-17 spacecraft carried a set of multi-band penetrating detection radar, that is, the ALSE lunar detection radar (Apollo Lunar Sounder Experiment). Geological structure data within the depth range of 1-2km. However, due to the limitations of the development level of electronic technology at that time, the detection results of the radar had many defects, mainly in...

AI Technical Summary

Problems solved by technology

The LRS radar system gives the distribution of the geological structure of the lunar crust within the range of hundreds of meters to kilometers under the lunar surface, but the resolution of the geological layers is relatively poor

[0004] It can be seen that the radar systems that have been used to detect the subsurface structure of the moon are all installed on orbital probes in the outer space of the moon. Due to the limitation of equipment installation space and detection technology, the resolution of detection results is low
