Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Area of Science:

Planetary Science
Geophysics
Radar Remote Sensing

Background:

The Chang'e 4 mission's Yutu-2 rover utilizes the Lunar Penetrating Radar (LPR) to study the lunar subsurface.
Interpreting LPR data requires advanced signal processing to overcome noise and computational challenges.

Purpose of the Study:

To apply a microwave tomographic approach to LPR data for enhanced subsurface imaging.
To compare two distinct tomographic methods for modeling signal propagation at the lunar air-soil interface.

Main Methods:

A two-step signal processing pipeline was employed, including time-domain pre-processing for noise and clutter reduction.
Microwave tomography was utilized to address computational issues associated with the large probing domain.
Two tomographic approaches differing in air-soil interface propagation modeling were evaluated.

Main Results:

Tomographic images were generated along a 1340 m traverse route.
The images successfully identified significant subsurface geometrical features.
These findings align with geological interpretations from previous research.

Conclusions:

Microwave tomography is an effective technique for analyzing Lunar Penetrating Radar data.
The study confirms the presence of complex subsurface structures on the Moon.
The results support and enhance existing geological models of the Chang'e 4 landing site.
