Diagnosis of defective elements in steerable antenna arrays by means of a non-standard regularization approach

The possibility of detecting faulty elements in steerable antenna arrays based on measurements of the radiated electromagnetic field has a key relevance in several scenarios. However, since the related inverse problem is affected by a severe ill-posedness, the development of specific algorithms is required for its solution. In this contribution, the problem is solved through a non-standard regularization approach formulated outside the common framework of Hilbert spaces. The algorithm is validated in the presence of numerically simulated data.
