DOA Estimation based on the Optimized Coprime Array Configuration
IEEE Access, 2019 In this paper, a direction-of-arrival (DOA) estimation based on the optimized coprime array (OpCA) configuration is proposed. The proposed array, utilizing the two constituting subarrays N-array and M-array of the coprime array, where their sensors are N

Underdetermined Wideband DOA Estimation for Off-Grid Sources with Coprime Array Using Sparse Bayesian Learning [PDF]
Sensors, 2018 Sparse Bayesian learning (SBL) is applied to the coprime array for underdetermined wideband direction of arrival (DOA) estimation. Using the augmented covariance matrix, the coprime array can achieve a higher number of degrees of freedom (DOFs) to ...

Generalized coprime array configurations [PDF]
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014 A coprime array consists of two uniform linear subarrays that construct an effective difference co-array with certain desirable characteristics. In this paper, we propose a generalized coprime array concept through the compression of the interelement spacing of one constituting subarray.

Passive beamforming with coprime arrays
IET Radar, Sonar & Navigation, 2017 Coprime arrays have been recently proposed as effective sparse configurations suitable for radar beamforming and angle‐of‐arrival estimation applications. In this study, a new approach for passive beamforming using coprime arrays is presented. In particular, a new detection strategy is proposed, which outperforms the coprime processors presently ...
