Abstract
Existing assumptions and approximations sometimes remain unjustified since the scattering phenomenon is not fully understood. Experimental techniques need improvement and advancement to make a contribution to the research of a mathematical model that describes the scattering process. To satisfy this need, a fully polarimetric bistatic-scattering system has been constructed and serves as a tool to better describe wave interaction with random media in this paper. To meet both the size and design constraints, a horn antenna operating in the far field and a parabolic-dish antenna operating in the near field focus mode are utilized. The transmitter for the active system is a linearly polarized, helium-neon laser. The receiver measures both like- and cross-polarized returns. This helps assess the scattered radiation pattern. Experimental measurements for a target are presented to evaluate the accuracy, repeatability, and utility of the system.
