摘要

提出并构造了一种改进的协素数阵列(CA)，称为扩展协素数阵列(ECA)，以减少传统协素数阵列和差分阵列之间传感器的重叠，从而得到具有高自由度的和差分阵列。所设计的ECA是将CCA的一个子阵列进行移位以减少冗余，然后将移位的子阵列的一部分围绕作为对称中心的零点翻转。所构建的ECA以较低的相互耦合扩展了元件间的分离。通过数值仿真验证了所设计的ECA的优越性。

Extended Coprime Arrays with Sum-Difference Coarray for DOA Estimation

A modified coprime array (CA) with a name of extended CA (ECA) is presented and constructed to reduce over-lapping sensors between sum and difference coarray using conventional CA (CCA) to get a sum-difference coarray with high degrees- of-freedoms (DOFs). The devised ECA is to shift a sub array of CCA to reduce redundancy and then to flip part of shifted sub array around zero point that is regarded as symmetric center. The onstructed ECA expands the inter-element separations with lower mutual coupling. Numerical simulation are provided to verify superiority of the devised ECA.
