In this paper, we introduce two further dilations of the recently introduced dilated nested arrays (DNAs), which possess an equal virtual ULA part to that of the nested arrays but possess two dense physical ULAs with the critical spacing (2 × λ/2). With having the parent array number of uniform DOFs…
In this paper, we present a new sparse co-prime array design that achieves a higher number of degrees-of-freedom for direction-of-arrival (DOA) estimation. The proposed array design adopts a sequence of displacements applied in a systematic procedure to the sensors of one of the two constituent sub-…
The recent criteria of a preferable linear sparse array for a robust direction of arrival (DOA) estimation are the closed-form expression for its sensor locations, the large central uniform linear array (ULA) segment in its resulting co-array and the fewer sensor pairs with small separations in its…
