Direction of arrival (DOA) estimation from the perspective of sparse signal representation
has attracted tremendous attention in past years, where the underlying spatial sparsity …

In this article, a general introduction to the area of sensor array and multichannel signal
processing is provided, including associated activities of the IEEE Signal Processing Society …

A class of low-complexity compressive sensing-based direction-of-arrival (DOA) estimation
methods for wideband co-prime arrays is proposed. It is based on a recently proposed …

In this paper, we analyze the effect of nonuniform array configurations on adaptive
beamforming for enhanced signal-to-interference-plus-noise ratio (SINR). The array is …

An effective sparse array extension method for maximizing the number of consecutive lags
in the fourth-order difference co-array is proposed, leading to a novel enhanced sparse …

The paper considers sparse array design for receive beamforming achieving maximum
signal-to-interference plus noise ratio (MaxSINR) for both single point source and multiple …

Based on the high-order difference co-array concept, an enhanced four-level nested array
(E-FL-NA) is first proposed, which optimizes the consecutive lags at the fourth-order …

We develop sparse array receive beamformer design methods achieving maximum signal-to-
interference plus noise ratio for wideband sources and jammers. Both tapped delay line …

Rotman lenses are the beguiling devices used by the beamforming networks (BFNs). These
lenses are generally used in the radar surveillance systems to see targets in multiple …

Multiband antenna arrays have the capability of effectively working in multiple frequency
bands and thus significantly simplify the antenna system. To further reduce the system …
