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

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.
