Abstract
Low side lobe level (SLL) and forming nulls can help to realize high-frequency (HF) superdirective receive arrays. In this letter, we reformulate the problem of designing an HF superdirective receive array as a problem of pattern synthesis. Based on the adaptive array theory, we present a numerical pattern synthesis algorithm combined with the design of HF superdirective receive array. Compared with the existing methods for superdirective array design, new method has more advantages in suppressing interferences and clutter. To confirm the effectiveness of novel method, numerical simulations are conducted.
