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.

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 and 2M, respectively, shifts all the sensors of the M-array by a specific displacement amount Ls ...

New Cramér-Rao bound expressions for coprime and other sparse arrays
, 2016 The Cramér-Rao bound (CRB) offers a lower bound on the variances of unbiased estimates of parameters, e.g., directions of arrival (DOA) in array processing. While there exist landmark papers on the study of the CRB in the context of array processing, the

COPRIME ARRAYS WITH ENHANCED DEGREES OF FREEDOM
Anadolu 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.
