In two-dimensional direction of arrival (2D-DOA) estimation, planar arrays can estimate the
elevation and azimuth angles simultaneously. However, many planar array topologies such …

Ship target detection using radar is an important application in military and civilian fields. For
the polarization estimation of scattering waves in the underdetermined case, that is, the …

Sparse arrays can provide superior resolution in direction‐of‐arrival (DOA) estimation with
limited number of sensors. Two‐dimensional (2D) arrays are fundamental to localization …

The millimeter wave (mmWave) channel is dominated by line-of-sight propagation.
Therefore, the acquisition of angle-of-arrival (AoA) and polarization state of the wave is of …

In this paper, a new array structure of sparse nested array (SNA) for electromagnetic vector
sensor is designed. An electromagnetic vector sensor is composed of six spatially colocated …
