Claim 2:
3. The three-dimensional co-prime cubic array direction-of-arrival estimation method based on a cross-correlation tensor according to claim 1, wherein the second-order cross-correlation tensor statistics of the three-dimensional co-prime cubic array in step (3) are estimated by calculating cross-correlation statistics of T sampling snapshots of the receiving signal tensors (t) and (t) in reality:, ℛ
