Cross-polarization measurements and their relation to target surface properties

It has often been suggested in lunar studies that measurements of radar cross-polarization factor should yield information on the target\´s surface roughness and dielectric properties. This paper describes an experimental effort to obtain quantitative data on , the average value of , for randomly rough targets having Gaussian distribution of slopes. Bistatic -band microwave measurements were conducted on targets with different dielectric constants but identical rough surfaces, and targets with same dielectrics but different statistics. The dependence of on various parameters is shown graphically, and extension to M.I.T. data of lunar crosspolarization is discussed.
