Integrated sensing and communications (ISAC) has attracted tremendous attention for the
future 6G wireless communications systems. To improve the transmission rates and sensing …

The signal processing community is currently witnessing the emergence of sensor array
processing and direction-of-arrival (DoA) estimation in various modern applications, such as …

One of major challenges in applying traditional subspace-based direction finding techniques
to real-time practical problems is in that they normally require an exhaustive spectral search …

We present a source localization method based on a sparse representation of sensor
measurements with an overcomplete basis composed of samples from the array manifold …

A class of subspace-based methods for direction-of-arrival (DOA) estimation and tracking in
the case of uniform linear arrays (ULAs) with mutual coupling is proposed. By treating the …

A new spectral search-based direction-of-arrival (DOA) estimation method is proposed that
extends the idea of the conventional ESPRIT DOA estimator to a much more general class of …

This paper presents a new computationally efficient method for direction-of-arrival (DOA)
estimation with arbitrary arrays. The total angular field-of-view is first divided into several …

The problem of direction-of-arrival (DOA) estimation in partly calibrated arrays is addressed.
We assume that an array is composed of multiple well-calibrated subarrays of arbitrary …

In this paper, the problem of spectral search-free direction-of-arrival (DOA) estimation in
arbitrary nonuniform sensor arrays is addressed. In the first part of the paper, we present a …

Array resolution limits and accuracy bounds on the multitude of signal parameters (eg,
azimuth, elevation, Doppler, range, cross-range, depth, frequency, chirp, polarization …
