An Off-axis Pole Focusing Method for Robust DOA Estimation in Multi-source Environments

Abstract

An off-axis pole focusing method for robust direction of arrival (DOA) estimation is presented in this paper. The roots (poles) of the root-MUSIC polynomial are generally evaluated over the unit circle in the z-domain. The DOAs can be computed from these poles using a simple geometric relation. Rather than computing the root-MUSIC polynomial over the unit… (More)
