Sparse DOA Estimation Based on Multi-Level Prime Array With Compression

IEEE Access, 2019
A signal emitter can be located using diverse types of direction finding (DF) techniques. One of the most widely used techniques is the direction of arrival (DOA) estimation using antenna arrays.

Direct Position Determination of Non-Circular Sources Based on a Doppler-Extended Aperture With a Moving Coprime Array

IEEE Access, 2018
Direct position determination (DPD) is a new promising technique in wireless location. Compared with conventional two-step localization methods, DPD achieves a higher accuracy by directly estimating the source location without computing the intermediate ...

Direction‐of‐arrival estimation in coprime linear array using three uniform linear arrays considering mutual coupling

IET Radar, Sonar & Navigation
Nowadays, sparse arrays have been a focus for direction‐of‐arrival (DOA). The existing arrays can achieve high degree of freedom (DOF) bigger than the number of sensors when using the spatial smoothing methods.

Novel coprime MIMO configurations for DOA estimation with increased degrees of freedom

Franklin Open
In this work, we propose some coprime multiple input multiple output (MIMO) configurations for direction-of-arrival (DOA) estimation, which achieve more degrees of freedom (DOF) than all the existing coprime MIMO configurations. We know that in a coprime
