Tensor Approach to DOA Estimation of Coherent Signals with Electromagnetic Vector-Sensor Array [PDF]
This paper addresses the direction-of-arrival (DOA) estimation problem using a uniform rectangular array with electromagnetic vector-sensors in correlated/coherent signal environments. The polarization information is separated from the steering matrix to

An Enhanced Spatial Smoothing Technique of Coherent DOA Estimation with Moving Coprime Array
This paper investigates the direction of arrival (DOA) estimation of coherent signals with a moving coprime array (MCA). Spatial smoothing techniques are often used to deal with the covariance matrix of coherent signals, but they cannot be used in sparse

Multiple autonomous underwater vehicles (AUVs) have gradually become the trend in underwater operations. Identifying and detecting these new underwater multi-targets is difficult when studying underwater moving targets. A 28-element transducer is used to

Detection of underwater coherent interference is necessary as its presence affects the estimation of the desired target. In this work, a method based on high-order particle velocity gradient polarization characteristics is proposed to distinguish the ...

Efficient DOA Estimation for Wideband Sources in Multipath Environment
A novel direction-of-arrival (DOA) estimator is proposed for the mixed uncorrelated and correlated wideband sources in the multipath environment. Firstly, the novel signal model is established using the aligned envelope technique. Next, the estimator can

Up to date, investigation of direction of arrival (DOA) gains more effort on multiple signals rather than coherent signals, particularly coherent signals measured by non-uniform and circular arrays — which still remains room for exploration.

An Oblique Projection-Based Beamforming Method for Coherent Signals Receiving
Within a complex sea or ground surface background, multipath signals are strongly correlated or even completely coherent, which leads to signal cancellation when conventional optimal beamforming is performed.

This paper considers the coherent integration problem for a low-observable maneuvering target, where the velocity and acceleration result in range migration (RM) and Doppler frequency migration (DFM) within the coherent pulse interval.

A fully-coherent all-sky search for gravitational-waves from compact binary coalescences [PDF]
We introduce a fully-coherent method for searching for gravitational wave signals generated by the merger of black hole and/or neutron star binaries.
