Sparse Cylindrical Arrays Based on the Low-Discrepancy Sobol Sequence Sampling

Sparse cylindrical arrays have grating lobe issues. Aperiodic spacing can reduce the grating lobes, however random approaches typically increase the average sidelobe level in addition to creating element clumping problems. This paper explores the use of a deterministic low discrepancy quasi-random distribution. The implementation of Sobol sequence on cylindrical platforms is outlined and we present numerical results for sparse array that are capable of removing the grating lobes.
