Abstract :
Stokes vector analysis of recent high-resolution observations of the lunar surface from the Arecibo Observatory have yielded estimates of the circularly and linearly polarized components of the backscatter signal. The linearly polarized component appears to be generated from the difference in the surface transmission coefficients associated with sub-surface scattering. The orientation of this component is correlated with the local plane of incidence and so provides a new method of estimating surface topography in the cross-range direction
