Array Failure Diagnosis Using Nonconvex Compressed Sensing

The array diagnosis technique based on nonconvex compressed sensing approach is introduced for a uniform linear array. In this sense, l
_p
minimization problem with p <; 1 is proposed for array diagnosis problem and it is solved using a weighted least squares approach. The proposed approach locates the faulty elements using less far-field measurements compared to the standard l
₁
minimization.
