Abstract:

An experiment was designed to study the effects of material type and configuration on Optical Cross Section OCS and spectrum. The experiment was conducted at an Air Force Research Laboratory AFRL far-field imaging facility, using different diffuse and specular materials and various configurations andor combinations of each. It was hypothesized that the OCS of certain combinations of materials is dependent on the diffuseness or specularity of the materials used, but the spectrum is independent of these factors and does not change. The objective of the experiment is to capture both OCS and spectra of different material configurations using different combinations of diffuse and specular materials in the bistatic illumination condition. OCS was calculated relative to the scattering of a Spectralon material that was in the scene during all data collects. Results show the accuracy of the above hypothesis and other effects that material type and configuration have on OCS and spectra.
