Failure correction of antenna arrays using convex optimization

In this article, a convex optimization method for failure correction of impaired antenna arrays is proposed. The number of elements to be corrected is iteratively minimized through the reweighted L1-norm algorithm while the corrected radiation pattern can be also ensured to be nearly consistent with the original one. Numerical results of a linear and a planar array correction demonstrate the better performance of the proposed method in terms of pattern consistency, number of corrected elements, and iteration speed compared with the state-of-the-art techniques.
