Modified DOA Estimation With an Unfolded Co-Prime Linear Array [PDF]
IEEE Communications Letters, 2019 Direction-of-arrival (DOA) estimation with unfolded co-prime linear arrays has been investigated thanks to the large aperture, excellent performance, and full degrees-of-freedom (DOFs). Besides, it has been admitted that the ambiguity problem can be suppressed thanks to the co-prime property. However, it is not always true. When there are two different
