Rectangular Thinned Array Design by McFarland Difference Sets

The problem of reducing the number of elements of large arrays is of great importance in satellite, remote sensing, radar and biomedical imaging applications in which the cost, weight, power consumption, mutual coupling effects, HW and SW complexity have to be as low as possible. Thinned arrays, however, are known to exhibit high peak sidelobe levels (PSL) if not suitably designed [1]. As a consequence, design techniques able to control and reduce the PSL of non‐regular arrays have been subject of research since their introduction [1]‐[5].
