Accurate Ultra-Wideband Array Radar Imaging Using Four-Dimensional Unitary ESPRIT
IEEE Access, 2019 Adaptive signal processing techniques can estimate the directions of arrival (DOAs), ranges, and radial velocities of radar targets with high resolution when applied in the space, frequency, and time domains, respectively.

ESPRIT for multidimensional general grids
, 2018 We present a new method for complex frequency estimation in several variables, extending the classical (1d) ESPRIT-algorithm. We also consider how to work with data sampled on non-standard domains (i.e going beyond multi-rectangles)

Compressive Parameter Estimation for Sparse Translation-Invariant Signals Using Polar Interpolation [PDF]
, 2015 We propose new compressive parameter estimation algorithms that make use of polar interpolation to improve the estimator precision. Our work extends previous approaches involving polar interpolation for compressive parameter estimation in two aspects: (i)

EM-Esprit Algorithm for Direction Finding with Nonuniform Arrays [PDF]
2007 IEEE/SP 14th Workshop on Statistical Signal Processing, 2007 This paper deals with the problem of the Direction Of Arrival (DOA) estimation with nonuniform linear arrays. The proposed method is a combination of the Expectation Maximization (EM) and the ESPRIT methods. The EM algorithm interpolates the nonuniform array to an equivalent uniform array, and then, the application of ESPRIT is possible, in order to ...

Adaptive ESPRIT algorithm based on the PAST subspace tracker [PDF]
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003 The Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT) algorithm is a subspace-based analysis method used in source localization or frequency estimation, originally designed in a block signal processing context. In other respects, the Projection Approximation Subspace Tracker (PAST) is a fast and robust subspace tracking ...
