We propose modeling method for the wall through radar by using near-field GTD as a near-region target model and delayed path-length for multi-layered dielectric sheets. Radar image can be constructed by AF (array-factor), which is a kind of synthetic aperture imaging. For near-region target, we apply focusing procedure of optical ray to the AF summation and the wall through pass. Refraction coefficient of N-layered dielectric sheets is exactly derived as boundary wave problem and applied to the wall through radar imaging. Theoretical near-field AF images are compared with far-field model, traditional SAR (synthetic aperture radar) image, and measured data. Moreover we consider antenna beam patterns. |
