Abstract

A high resolution DOA estimation technique in the presence of noise with unknown covariance matrix has been provided. This method provides high resolution at a reasonable computational burden. In this paper, a performance analysis of the DOA estimates obtained by this technique is provided using perturbation theory. Simulation results are presented to compare with the theoretical results. They show very good agreement.
