By radar backscattering, observations of the moon have been made which show a systematic difference between the backscattering coefficient of waves polarized in, and perpendicular to, the local plane of incidence. The results arein agreement with a model consisting of a tenuous top layer at least 10 centimeters thick, supported by a denser underlying layer.
