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

Sparse arrays are known to achieve an increased number of degrees-of-freedom (DOFs) for
direction-of-arrival (DOA) estimation, where an augmented virtual uniform array calculated …

Coprime arrays can achieve an increased number of degrees of freedom by deriving the
equivalent signals of a virtual array. However, most existing methods fail to utilize all …

We propose a high-resolution imaging radar system to enable high-fidelity four-dimensional
(4D) sensing for autonomous driving, ie, range, Doppler, azimuth, and elevation, through a …

A coprime array uses two uniform linear subarrays to construct an effective difference
coarray with certain desirable characteristics, such as a high number of degrees-of-freedom …

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, nonuniform linear arrays (eg, coprime/nested array) have attracted great attention
of researchers in array signal processing field due to its ability to generate virtual difference …

Sparse arrays such as nested and coprime arrays use a technique called spatial smoothing
in order to successfully perform MUSIC in the difference-coarray domain. In this paper it is …

Joint communication and radar (JCR) waveforms with fully digital baseband generation and
processing can now be realized at the millimeter-wave (mmWave) band. Prior work has …

In this letter, we propose a coprime array interpolation approach to provide an off-grid
direction-of-arrival (DOA) estimation. Through array interpolation, a uniform linear array …
