摘要：
A cumulant-based approach to broadband DOA estimation for Gaussian and non-Gaussian noises is presented. The approach is based on the fourth-cumulants of the array data in frequency domain, and relies on the statistical central limit theorem to show that the fourth-order cumulants of the additive non-Gaussian noises approach zero in focused noise space. Computer simulation results demonstrate the effectiveness of this new approach.
