Abstract
In this paper, we propose a Vectorized Conjugate Augmented MUSIC (VCAM) method which can construct an extended co-array named as diff-sum co-array. The diff-sum co-array comprises not only the difference co-array but also the sum co-array. Taking coprime array as the array model, we find all the holes in the difference co-array can be filled up by the elements in the sum co-array so that the diff-sum co-array contains more consecutive lags than the difference co-array. In particular, we discuss the complementarity between the difference and sum sets, and derive consecutive range of the diff-sum co-array. Simulations verify the effectivity of the proposed method.
