Array diagnosis from far field data via ℓ1 minimizations

In this contribution the use of ℓ₁ minimization for the diagnosis of arrays from far-field data is investigated. Numerical results show that reweighted method gives a higher probability of an accurate estimation of the failures compared to the classic ℓ₁ minimization proposed in the past literature, confirming the results obtained by the authors in the framework of near-field measurements.
