By illuminating Venus with circularly polarized radiation at 70-cm wavelength and observing the back- scattered echo, the polarized circular diffuse scattering laws were measured for incidence angles up to 90 . After correcting for atmospheric effects, it was found that at large incidence angles both scattering laws have a cosn 0 dependence with n very close to 1.7. In addition, the degree of linear polarization of the received echo was measured as a function of the incidence angle along the apparent rotation axis. This was found to be very much smaller than for the Moon, indicating very little subsurface reflection, and to have an angular dependence not increasing monotonically with 0. A model is proposed to explain this effect.
