Inverse-Based Approaches for Fault Detection in Antenna Arrays

Diagnosis of faulty elements in antenna arrays is nowadays attracting a relevant attention in the scientific community. Indeed, due to the high dimensionality of the arrays and to the higher working frequencies required in new applications, proper diagnostic procedures are required. In this framework, the present paper presents two new strategies, based on the matrix method and on regularization in non-conventional Lebesgue spaces, that can effectively address this task. Preliminary results are presented.
