In this letter, an ESPRIT-based algorithm is proposed to handle the direction of arrival (DOA)
estimation problem for strictly noncircular sources with unknown mutual coupling. At the cost …

In this paper, an efficient method via unitary joint diagonalization is proposed to deal with the
coherently distributed sources in bistatic multiple-input multiple-output (MIMO) radar …

Based on the quaternion theory, a novel algorithm named non-circular augmented
quaternion MUSIC (NCAQ-MUSIC) is proposed for DOA and range estimation of noncircular …

To locate mixed far-field (FF) and near-field (NF) sources, most existing methods require two
or three steps to first find the direction-of-arrival (DOA) and then retrieve the range …

A novel DOA estimation method for known waveform sources with different unknown time
delays and Doppler shifts is proposed. Based on the idea of maximum likelihood and the …

In this paper, we employ the geometry of uniform circular array to achieve classification and
localization of mixed near-field and far-field sources. Considering that the …

It is well known that the presence of non-circular signals can provide extra degrees of
freedom for a sensor array system, which can then be exploited for improved performance …

Digital communication signals in wireless systems may possess noncircularity, which can be
used to enhance the degrees of freedom for direction-of-arrival (DOA) estimation in sensor …

To effectively find the direction of non-circular signals received by a uniform linear array
(ULA) in the presence of non-negligible perturbations between array elements, ie, mutual …

In this paper, a joint diagonalization based two dimensional (2D) direction of departure
(DOD) and 2D direction of arrival (DOA) estimation method for a mixture of circular and …
