Advantages of nonuniform arrays using root-MUSIC [PDF]
Signal Processing, 2010 In this paper, we consider the Direction-Of-Arrival (DOA) estimation problem in the Nonuniform Linear Arrays (NLA) case, particularly the arrays with missing sensors. We show that the root-MUSIC algorithm can be directly applied to this case and that it can fully exploit the advantages of using an NLA instead of a Uniform Linear Array (ULA).

Approximate maximum likelihood estimation of two closely spaced sources [PDF]
, 2014 The performance of the majority of high resolution algorithms designed for either spectral analysis or Direction-of-Arrival (DoA) estimation drastically degrade when the amplitude sources are highly correlated or when the number of available snapshots is

Real-Valued DOA Estimation for Non-Circular Sources via Reduced-Order Polynomial Rooting
IEEE Access, 2019 A novel real-valued algorithm of the popular root multiple signal classification of non-circular sources (NC-root-MUSIC) is developed for low-complexity direction of arrival (DOA) estimation.

An IDFT-based root-MUSIC for arbitrary arrays [PDF]
2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010 Root-MUSIC algorithm, designed for uniform linear arrays, has been extended to arrays of arbitrary geometry by means of manifold separation techniques but at the cost of increased computational complexity. In this paper, an inverse discrete Fourier transform (IDFT)-based method is proposed in which polynomial rooting is avoided.
