| Abstract: | We continue to develop a technique based on the generalised likelihood-ratio test (GLRT) that is capable of identifying and rectifying direction-of-arrival (DOA) estimation outliers that arise with the use of any subspace-based DOA estimation technique. While our previously introduced likelihood ratio (LR) maximisation techniques relied upon specific properties of an assumed Toeplitz covariance matrix, in this paper we introduce a technique applicable to arbitrary antenna array geometries. | ||
