A high-resolution map of lunar radar reflectivity is presented which was obtained at a wavelength of 7.5 m with a radar resolution of 25 to 40 km by a combination of delay-Doppler radar techniques and interferometry. The results are given in the forms of a radar map of normalized echo power and plots of average scattering. A consistent difference in scattering between maria and terrae is observed, along with small differences in scattering between eastern and western maria. Specifically, it is found that the terrae reflect two to four times as much power as the maria, that the weakest echoes come from the youngest and western maria, that a few terra areas have suprisingly weak echoes, and that the average scattering behavior at 7.5 m is remarkably close to the behavior at 68 cm. The results also indicate that the large rayed craters have relatively weak enhancements of 1 to 1.5 over their environs, that the maria and terrae have essentially the same backscattering behavior as a function of incidence angle, and that the average scattering behavior of the moon and the limb darkening at 7.5 m are similar to those at 68 cm.
