- Abstract
This paper aims at subsurface imaging a target buried in a spherical homogeneous medium. In order to study it, a monochromatic holographic penetrating radar with high resolution is involved. Different from the target in the plane media, spherical ones always result in spherical interference fringes which awfully deteriorate the imaging quality. To solve this problem, this paper propose two methods and make a brief comparison. As we all know, radar echo mainly consists of direct wave and target echo. Due to the symmetry of the spherical interface, the direct wave and target echo are quite different in spatial spectrum domain distribution, and thus by using the first method, one can extract the target echo. The radar is placed right above the spherical interface, and samples thousands times along homocentric path. Therefore, direct wave varies very slowly and target echo is a sparse matrix. Then, a smoothing filtering can extract the direct wave. As a consequence, the remaining part is nearly the target echo. Furthermore, experiments are designed and validate the availability of proposed methods. What's more, a brief comparison between two methods is provided.
