Designing sparse cylindrical arrays without grating lobes is a challenging task due to the large element spacings. Aperiodic spacing can reduce the grating lobes, however random approaches typically increase the average sidelobe level. This paper explores the use of nonuniform element spacing based on the low-discrepancy Van der Corput sequence. Array pattern results are presented for cylindrical arrays with element spacings larger than one wavelength and we show that this approach is capable of removing the grating lobes.

Abstract

Designing sparse cylindrical arrays without grating lobes is a challenging task due to the large element spacings. Aperiodic spacing can reduce the grating lobes, however random approaches typically increase the average sidelobe level. This paper explores the use of nonuniform element spacing based on the low-discrepancy Van der Corput sequence. Array pattern results are presented for cylindrical arrays with element spacings larger than one wavelength and we show that this approach is capable of removing the grating lobes.
