Abstract

An effective probe compensated near-field-far-field transformation technique from irregularly spaced near-field data acquired via the recently proposed planar-wide-mesh-scanning is developed in this work. The singular value decomposition method is applied for recovering the uniformly distributed samples, whose position is fixed by a nonredundant sampling representation of the electromagnetic field. Then an optimal sampling interpolation algorithm is used to reconstruct the plane-rectangular data required to carry out the standard near-field-far-field transformation. Numerical examples are reported to assess the effectiveness of the proposed technique.
