Cross-track synthetic aperture radar (SAR) interferometry is a powerful technique that
analyzes the phase shift each pixel undergoes between acquisitions of the same scene with …

The quintessential goal of sensor array signal processing is the estimation of parameters by
fusing temporal and spatial information, captured via sampling a wavefield with a set of …

Array processing involves manipulation of signals induced on various antenna elements. Its

In this paper, we address the prospects and key enabling technologies for highly efficient
and accurate device positioning and tracking in fifth generation (5G) radio access networks …

Subspace estimation plays an important role in a variety of modern signal processing
applications. We present a new approach for tracking the signal subspace recursively. It is …

Subspace-based methods suffer from the rank loss of the noise free data covariance matrix
in the context of direction of arrival (DOA) estimation of coherent sources. The well-known …

This paper links multiple invariance sensor array processing (MI-SAP) to parallel factor
(PARAFAC) analysis, which is a tool rooted in psychometrics and chemometrics. PARAFAC …

The use of smart antennas to increase mobile communications channels has re-ignited
