Localization of Cylinders by Near-Field Multibistatic Measurements

The problem of localizing both conductive and dielectric cylinders of arbitrary known radius is dealt with in a 2-D geometry. A reflection-mode multifrequency multibistatic configuration is considered. The problem is formulated in the near zone, and a linear inversion algorithm based on the truncated singular value decomposition is proposed. The algorithm is validated against experimental data, allowing assessing the expected performances of the approach.
