Array Diagnostics, Spatial Resolution, and Filtering of Undesired Radiation with the 3D Reconstruction Algorithm

10 Sep 2013

This paper focuses on three important features of the 3D reconstruction algorithm of DIATOOL: the identification of array elements improper functioning and failure, the obtainable spatial resolution of the reconstructed fields and currents, and the filtering of undesired radiation and scattering to obtain a more accurate measured field. Results obtained by real measured data are presented.

Special attention is given to the computational advantages given by the higher-order Method of Moments-based formulation of DIATOOL. Guidelines on the recommended measurement sampling and measured field truncation for achieving the best possible reconstruction results are also provided.
