Abstract
This work deals with the design of contiguously clustered linear phased arrays matching user‐defined requirements in terms of far‐field radiated pattern. Towards this aim, a novel total‐variation compressive sensing (TV‐CS) methodology has been developed and customized to the problem at hand such that the sparsity of the gradient of the array excitations is maximized. Thanks to such an approach, it is possible to obtain highly‐performing designs with a reduced number of sub‐arrays. Some numerical results are shown to assess the proposed TV‐CS method when dealing with the clustering of linear arrays radiating Taylor patterns with different requirements on the side‐lobe level (SLL).
