We construct a bistatic polarimetric scattering system and improve the experimental techniques to contribute to the research of a mathematical model that describes the electromagnetic waves scattering characteristics from random rough surfaces, and to serve as a tool used to better describe wave interaction with random media. To accomplish the measurement both 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 operating in the red light region. The receiver measures both like- and cross-polarized returns, which helps assess the scattered radiation pattern. Aflat metal plate is developed to calibrate the measuring facility. The system is automated and consists of a spherical frame over which the transmitter and receiver travel. The transmitter and receiver design, system automation, and system architecture are discussed. Experimental measurements for a target are presented to evaluate the accuracy, repeatability, and utility of the helium-neon laser measurement system.
