An iterative root-MUSIC for 2-D angle estimation

ISSPA '99. Proceedings of the Fifth International Symposium on Signal Processing and its Applications (IEEE Cat. No.99EX359), 2003
We propose a root-MUSIC algorithm implemented in an iterative fashion for 2-D angle estimation, based on a circular array. The algorithm is computationally more efficient than an existing spectral-MUSIC algorithm, at no loss of accuracy.

The method of spectral resolution root-MUSIC has been considered recently as one of the means to solve the problem of increasing the accuracy of measuring the elevation of lowaltitude targets above rough sea. However, the traditional approach to the selection of a priori parameters of the method developed with spectral analysis does not reveal its ...

Imaging by Root-MUSIC for forward looking radar with linear array

2013 International Conference on Wireless Communications and Signal Processing, 2013
The azimuth resolution of forward looking radar is limited. Aiming at forward looking radar with linear array, the azimuth signal is modeled as the sum of exponents and a super-resolution algorithm based on Root-MUSIC is presented. With the estimation of Doppler frequency in each range cell, the coordinates of scatterers can be calculated. Finally, the

Development, performance analysis, and experimental evaluation of beamspace Root-MUSIC

[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991
A computationally efficient beamspace implementation of Root-MUSIC is developed. The algorithm exploits the common out-of-band nulls property exhibited by discrete Fourier transform (DFT) beams. For each set of B successive DFT beams encompassing a given spatial sub-band, the major computations are an eigenvalue decomposition of the real part of the B ...

The root-MUSIC algorithm for direction finding with interpolated arrays

Signal Processing, 1993
Abstract This paper presents a direction finding technique which uses the outputs of a virtual array, computed from the real array using a linear interpolation procedure over a given sector. The geometry of the virtual array is under the control of the designer. By using a linear virtual array, the root-MUSIC algorithm can be applied, even though the

Matrix beamforming preprocessor for beamspace Root-MUSIC

[Proceedings] 1992 IEEE International Symposium on Circuits and Systems, 2003
The author considers the problem of interpolating a synthetic or virtual linear equispaced (LES) array from a real irregular array to effect some algebraic direction-finding technique such as Root-MUSIC. The interpolation of a virtual LES array can be accomplished through the use of a matrix beamforming preprocessor connected to the output of the real ...

Computation of spectral and root MUSIC through real polynomial rooting

IEEE Transactions on Signal Processing, 2005
We present a technique to compute the Spectral and (Unitary) Root MUSIC estimations from the roots of a real polynomial in the problem of estimating the angles of arrival to a Uniform Linear Array (ULA). The computed estimations are the actual MUSIC or (Unitary) Root MUSIC estimations, but the need for a one-dimensional (1-D) search in Spectral MUSIC ...
