Existing sparse array (SA) geometries, such as coprime and nested arrays, can be regarded as a concatenation of two uniform linear arrays (ULAs). Such arrays lead to a significant …
P Zhao, G Hu, Z Qu, L Wang - IEEE Communications Letters, 2019 - ieeexplore.ieee.org
In this letter, we propose an enhanced nested array (ENA) configuration consisting of two uniform linear arrays (ULAs) with different separations and an additional sensor, whose …

In this work, we present a new coprime array structure termed thinned coprime array (TCA), which exploits the redundancy in the structure of existing coprime array and achieves the …
Q Shen, W Liu, W Cui, S Wu - IEEE Signal Processing Letters, 2016 - ieeexplore.ieee.org
An effective sparse array extension method for maximizing the number of consecutive lags in the fourth-order difference co-array is proposed, leading to a novel enhanced sparse …
