An overview about mutual coupling analysis in antenna arrays is given. The relationships
between array impedance matrix and embedded element patterns, including beam coupling …

Direction-of-Arrival (DOA) estimation concerns the estimation of direction finding signals in
the form of electromagnetic or acoustic waves, impinging on a sensor or antenna array. DOA …

A number of new and planned radio telescopes will consist of large arrays of low-gain
antennas operating at frequencies below 300 MHz. In this frequency regime, Galactic noise …

Autonomous teams of unmanned ground and air vehicles rely on networking and distributed
processing to collaborate as they jointly localize, explore, map, and learn in sometimes …

This work aims to estimate the polarization of fully polarized sources, given prior knowledge
of the incident sources' azimuth-elevation directions-of-arrival, using a pair of diversely …

The problem of beamforming based on hypercomplex processes is considered for an
airborne electromagnetic (EM) vector-sensor array. The quaternion domain facilitates …

A significant challenge in spectrum sensing is to lessen the signal to noise ratio needed to
detect the presence of primary users while the noise level may also be unknown. To meet …

One of the limiting factors in the performance of radar systems is the presence of mutual
coupling (MC) between receive antenna elements or array imperfections, such as antenna …

Antenna effects on a monostatic multiple-input-multiple-output (MIMO) Radar for direction
estimation are studied by analyzing the Cramèr-Rao lower bound (CRLB). The CRLB is …

Observations made using antenna arrays are often limited by the noise coming from the
antenna system itself and from the environment. In demanding applications such as radio …
