N2 - This communication deals with high-resolution direction finding using higher-order cumulants of the array data. Two 4th-order cumulant-based matrices are considered: the diagonal cumulant slice and the contracted quadricovariance. They are evaluated in the context of DOA estimation using "subspace" techniques. To this purpose, we introduce an original methodology to derive the closed form of asymptotical performance. This analysis is applied to the cumulant based DOA estimation problem, establishing on a rational basis the domain of applicability of HOS in DOA estimation which is larger than usually believed. It is also shown that the contracted quadricovariance outperforms the diagonal slice in all respects. Some numerical evaluations illustrate the results.
