Abstract
Surface roughness and backscattering enhancement of impact fragments are experimentally investigated. Reflected light from the surface of small solar system body shows an enhancement in backward direction, that is attributed to so-called shadow-hiding mechanism and coherent backscattering mechanism of particulate or rough surfaces. The laboratory results are discussed in comparison with the previous results of powdery surfaces and the observational data of backscattering properties of asteroids.
