Abstract

The librations of the Moon allow it to be mapped using a continuous wave radar by an aperture synthesis method particularly suited to long wavelengths. Maps, as seen in the depolarised return at wavelengths of 75 and 185 cm, are presented. Both are broadly similar and show that most of the depolarised return comes from the highland regions with no significant return from the maria. Certain isolated features, such as the craters Tycho, Theophilus, and Copernicus, appear particularly prominent.
