Triple extended coprime array for single‐snapshot DoA estimation

open access: yesElectronics Letters
The direction‐of‐arrival (DoA) estimation methods based on coprime array (CA) largely rely on having a sufficient number of snapshots. However, under single‐snapshot conditions typical of vehicle‐mounted imaging radar, CA‐based DoA estimation often ...

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

open access: yesIEEE 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 ...

COPRIME ARRAYS WITH ENHANCED DEGREES OF FREEDOM

open access: yesAnadolu University Journal of Science and Technology-A Applied Sciences and Engineering, 2018
Coprime array geometries provide robust performance for direction-of-arrival estimation problem with more sources than sensor elements. In previous works it is shown that K source directions can be resolved using only 2M + N -1 sensor elements where K is less than or equal to MN.

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

open access: yesIET 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.
