Reviewer 2 Report
The paper presents the problem of direction of arrival (DOA) estimation for massive multi-input multi-output (MIMO) radar, and propose a total array based multiple signals classification (TA-MUSIC) algorithm for two-dimensional direction of arrival (DOA) estimation with coprime cubic array (CCA).
Before being suitable for publication, the authors should address these minor comments:
- Please rework the X and Y axes of Figure 2.
- A comparison table between the proposed method and the previous works is welcome to complete the introduction section and highlight the novelties of the proposed method.
- A more detailed description and presentation of each of the result graphs would be appreciated
