ESPRIT target position estimation with uniform linear array and uniform circular array

Spatial Signature Estimation with an Uncalibrated Uniform Linear Array †

In this paper, the problem of spatial signature estimation using a uniform linear array (ULA) with unknown sensor gain and phase errors is considered. As is well known, the directions-of-arrival (DOAs) can only be determined within an unknown rotational angle in this array model. However, the phase ambiguity has no impact on the identification of the spatial signature. Two auto-calibration meth...

Cuba-esprit for Angle Estimation with Circular Uniform Beam Arrays

Currently, spatial signal processing for adaptive source separation and interference cancellation are extensively discussed for application in future mobile radio systems. ESPRIT-type algorithms are especially concerned because of their low arithmetic complexity and their inherent ability for superresolution estimation of the direction of arrival (DoA) [1]. The latter is also true for mobile ra...

Multiple target three-dimensional coordinate estimation for bistatic MIMO radar with uniform linear receive array

A novel scheme to achieve three-dimensional (3D) target location in bistatic radar systems is evaluated. The proposed scheme develops the additional information of the bistatic radar, that is the transmit angles, to estimate the 3D coordinates of the targets by using multiple-input multiple-output techniques with a uniform circular array on transmit and a uniform linear array on receive. The tr...

DOA and Polarization Estimation Using an Electromagnetic Vector Sensor Uniform Circular Array Based on the ESPRIT Algorithm

In array signal processing systems, the direction of arrival (DOA) and polarization of signals based on uniform linear or rectangular sensor arrays are generally obtained by rotational invariance techniques (ESPRIT). However, since the ESPRIT algorithm relies on the rotational invariant structure of the received data, it cannot be applied to electromagnetic vector sensor arrays (EVSAs) featurin...
