Analytic Techniques for the Design of Non-Regular Arrays

The cost, weight, power consumption, mutual coupling effects, HW and SW complexity of large arrays can be greatly reduced by suitable non-regular array design techniques, that is by considering array designs with a low number of elements with respect to that of a half‐wavelength equispaced array . Non‐regular arrays, however, are known to exhibit higher peak sidelobe levels (PSL) if not suitably designed. As a consequence, design techniques able to control and reduce the PSL of non‐regular arrays have been subject of research since their introduction.
