Integrated approach for efficient adaptive underdetermined DOA estimation: coarray LMS with covariance matrix error removal

Underdetermined direction of arrival (U-DOA) estimation relies on the higher degrees of freedom provided by the difference coarray of a non-uniform linear array.

Optimizing Minimum Redundancy Arrays for Robustness

, 2018
Sparse arrays have received considerable attention due to their capability of resolving O(N^2)uncorrelated sources with N physical sensors, unlike the uniform linear array (ULA) which identifies at most N−1 sources.

Flexible Extended Nested Array with Multiple Subarrays Achieving Improved Degrees of Freedom [PDF]

This paper proposes a new extended nested array geometry with enhanced degrees of freedom (DOF) and a hole-free difference co-array. The proposed flexible extended nested with multiple subarrays (f-ENAMS) configuration is constructed by splitting the ...
