DOA Estimation of Linear Dipole Array With Known Mutual Coupling Based on ESPRIT and MUSIC

Abstract: In this paper, multiple signal classification and estimation of signal parameters via rotational invariance technique (ESPRIT) algorithms are proposed to estimate the direction of arrival (DOA) of multiple incident signals under known mutual coupling among elements of the antenna array. These algorithms use the same subspace based techniques to achieve the separation of the eigenvectors into two subspaces: the signal space and the noise space. However, ESPRIT only uses the signal space. The performance of subs… Show more

“…A beamformer is a collection of antennas which are linearly arranged so that their output can be steered electronically. The received signal at these antennas is used to compute the complex weights which are adaptively updated based on signal samples [6]. The first part of the presented design is begun by calculating the covariance matrix.…”

“…In practice, interactions between the HWD antennas will result in mutual coupling, which distorts the ideal steering vector significantly. In this situation, the true steering vector should be modified, then the received signal x M (t) is give by [6]: We can write formula (1) in the following form:…”
