Fig. 5From: Estimation of bulk permittivity of the Moon’s surface using Lunar Radar Sounder on-board Selenological and Engineering ExplorerThe flowchart of data analysis of this study. ρ, p and δ1 denote density, porosity and loss tangent of the 1st layer, respectively, while ρgrain indicates the density pertaining to the solid material itself. As for ε1, σ1 and ε2, refer to the caption of Fig. 4Back to article page
