Coprime array offers a larger array aperture than uniform linear array with the same number
of physical sensors, and has a better spatial resolution with increased degrees of freedom …

Recently, many sparse arrays have been proposed to increase the number of degrees of
freedom for direction of arrival (DoA) estimation especially for circular signals. Though many …

Sparse sensor arrays have attracted considerable attention in various fields such as radar,
array processing, ultrasound imaging and communications. In the context of correlation …

An augmented coprime array systematically employs two sparse subarrays to produce a
large-scale difference co-array with attractive merits, such as enhanced degrees of freedom …

In this paper, we develop a general framework of multi-frequency sparse array to estimate
the direction-of-arrival (DOA) of a significantly higher number of targets than the number of …

We propose anew antenna array design approach for a multiple-input and multiple-output
(MIMO) radar, which has closed-form expressions for the sensor locations and the number of …

Two-dimensional (2D) arrays are fundamental to localization applications. Specifically,
sparse arrays can provide superior direction-of-arrival (DoA) estimation performance with …

Sparse arrays, such as nested arrays and coprime arrays, can achieve a high number of
degrees of freedom (DOFs) for direction of arrival (DOA) estimation with a reduced number …

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 …

In this work, we propose a novel strategy of adaptive sparse array beamformer design,
referred to as regularized complementary antenna switching (RCAS), to swiftly adapt both …
