摘要

In this letter, we investigate the issue of sparse array design for direction of arrival (DOA) estimation of non-circular (NC) signals, and propose the transformed nested array (TNA) which reduces overlapping virtual sensors between the difference and the sum co-array generated by the conventional nested array (NA) and can thus obtain a sum-difference co-array with higher degrees of freedom (DOFs)...
