Abstract

An innovative method for the synthesis of maximally sparse linear arrays matching arbitrary reference patterns is proposed. In the framework of sparseness constrained optimization, the approach exploits the multi-task Bayesian compressive sensing theory to enable the design of complex nonHermitian layouts with arbitrary radiation and geometrical constraints. By casting the pattern matching problem into a probabilistic formulation, a Relevance-Vector-Machine technique is used as solution tool. The numerical assessment points out the advances of the proposed implementation over the extension to complex patterns of [18] and it gives some indications about the reliability, flexibility, and numerical efficiency of the approach also in comparison with state-of-the-art sparse-arrays synthesis methods.
