Abstract
The photometric behavior of the Moon's surface describes how the reflected solar radiation varies with incidence,emission and solar phase angles, which is dependent on the physical and chemical properties of the lunar soils, such as particle size and shape, porosity, and mineralogical composition. Using the Chang'E-1 Interferometer Imager(IIM)Level 2A radiance data, the lunar surface is divided into two classes based on 2D histogram statistics with phase angle vs. radiance. The iron abundances for the two classes approximately agree with those for mar ia and highlands,respectively. The method is proved to be valid using the IIM data for highland(Apollo 16) and mare(Mare Serenitatis). The 2D histogram statistics method based on IIM 2A data could avoid errors introduced by data post-processing of the IIM data.
