Abstract
The work devoted to experimental investigation of polarization back-scattering characteristics square metal plates by the quasioptical waveguide modeling (QWM) method in the near-millimeter wave (NMMW) band. The polarimetric microcompact range (PMCR) was used for amplitude-phase scattering patterns measuring. PMCR created on the base of quasioptical transmission line, namely circular hollow dielectric waveguide (HDW), quasioptical and waveguide functional devices, and elements of SHF circuit has been used for amplitude-phase patterns of object scattering. The measured results of polarization scattering matrix (PSM) elements and their backscattering patterns (monostatic case) for a number of samples, namely thin metal plates of square cross-section have been presented. The patterns have been obtained for each plate in proper linear polarization basis. Comparison of experimental SMR elements patterns for plates in NMMW band with geometrical theory of diffraction (GTD) data was made.
