Radar array diagnosis from undersampled data using a compressed sensing/sparse recovery technique

A Compressed Sensing/Sparse Recovery approach is adopted in this paper for the accurate diagnosis of fault array elements fromundersampled data. Experimental validations on a slotted waveguide test array are discussed to demonstrate the effectiveness ofthe proposed procedure in the failures retrieval froma small set ofmeasurements with respect to the number of radiating elements.Due to the sparsity feature of the proposed formulation, the method is particularly appealing for the diagnostics of large arrays,typically adopted for radar applications.
