Abstract: The coarray techniques, e.g., nested and coprime arrays, can significantly improve degrees of freedom (DOFs) via constructing a so-called difference coarray, which enables underdetermined direction-of-arrival (DOA) estimation within reach in the presence of unknown nonuniform… read more here.

Abstract: Sparse linear arrays like nested arrays and coprime arrays, can offer more accurate direction-of-arrival estimation than uniform linear arrays by exploiting their difference coarrays. In this letter, we present a new algorithm for direction finding… read more here.
