 Silica sand on Rupat Island was identified using X-ray fluorescence, a Los Pulsar four-polarimetry data, dielectric constant measurements, and Freemander Dean and Yamaguchi techniques to obtain the scattering decomposition of physical scattering from an incoherent object model base. The backscattering coefficient value of silica sand ranged from minus 59 dB to minus 52 dB, with a thickness estimation of 59 centimeters to 74 centimeters and an average differentiation of 4.88 centimeters. The grain size of silica sand particles was tested using microscopic photograph testing, which caused slight roughness on the surface.
