A Study And Application On The Information Extraction Of Rock And Mineral On The Moon And Mars Based On Remote Sensing

Multi/hyperspectral remote sensing have been used to extract the information of rock and minerals, which is a hotspot and difficulty in the remote sensing geology field. This method can identify more minerals species and improve the reliability. In recent years, with the development of remote sensing technology, multi/hyperspectral rock extraction methods have been used on the Lunar and Mars. The methods have made achievements on the Lunar and Mars. The traditional methods of geological exploration are not very applicable to the planetary exploration, therefore, the use of remote sensing, remote detection of planets in the outer space has played a very important role to the Moon, Mars and other planets.In this paper, based on Clementine multi-spectral data of the Moon, TES and the CRISM data of the Mars, from three aspects of the information extraction of rock and mineral, data processing and multi/hyperspectral/thermal infrared emissivity data extraction, study the Moon and Mars and have achieved some results.The main content and research results of this paper are as follows:(1) Analyzing the spectral features of the minerals and rocks on the moon and earth, and comparing the mineral spectral of simulated lunar soil samples with the earth, studying the similarities and differences, analysis the reasons;(2) In this paper, according to the spectral absorption features, band ratio method was used to extract the information of the minerals of the typical impact craters and mares on the lunar surface. This paper got information extraction maps and summarized the distribution characteristics of olivine, plagioclase, iron and titanium in the crater and mares, which provided the basis for studying the relationship of the lunar surface mineralogy, geomorphology, stratigraphy.(3) By using Lucey's inversion model, it inverted the abundance of iron and titanium in Aristillus. The result was consistent with the result based on the ratio method. This also verified the applicability and reliability of both methods.(4) Using the Mars thermal infrared emissivity data-TES, based on the linear spectral separation, spectral fitting, mixture tuned matched filtering methods, and so on, extracted the mineral information on the Martian surface. This paper compared and analyzed the results, and compared the results with the foreign scholars, analyzed the existing differences and influencing factors.(5) This paper also used the hyperspectral data, CRISM data of the Mars, combining with SAM method, extracted the mineral information of the study area on the Mars surface. This paper had extracted olivine, illite, montmorillonite, kaolinite, muscovite, chlorite, and jarosite, and so on. CRISM data resolution is very high, which it not only plays an important role on the study of Martian geology, but also it is of great significance for the detection of Martian surface water.
