Abstract

We describe bistatic scattering measurements on eight reference targets constructed from Al₂O₃ grit of various sizes embedded in an absorptive epoxy matrix. These samples' surface topographies were measured using focus-variation microscopy, and their autocorrelation lengths and root-mean-square (RMS) roughness levels extracted. Bistatic scattering measurements were then performed in the principal plane over the 325-500 GHz range and at 650 GHz, using either a vector network analyzer or a narrow band source and detector respectively, in both s an p polarizations, and at incidence angles of 25^o, 45^o, and 65^o. The samples' root-mean-square (RMS)roughness levels cover the range of 36-280 υm, corresponding to 0.39
