Reflecting Surface

Determination of the physical properties of the surface layers of celestial bodies is one of the areas of research in radar astronomy. Radar pulses reflected from such a body contain information about the reflecting surface. Information concerning the composition and density of the outer layer of the lunar surface derived from radar echoes is of practical importance in view of proposed lunar landing.
