Round 1

Reviewer 1 Report

This paper presents interesting digital phased array based on shared subarray architecture. Please see below comments.

 

1. What is the cross-pol performance? Onyl co-pol performance is presented.

2. Could you show an array geometry or antenna type in consideration? Array antenna and its beamforming pattern is a strong function of antenna as discussed in the paper.

3. Could you discuss FPGA plaform for the proposed DBF?

Reviewer 2 Report

In this research article, the authors proposed an architecture with titled; "An Innovative Design of Isoflux Scanning Digital Phased Array Based on Completely Shared Subarray Architecture for Geostationary Satellites", the topic looks interesting but following are some comments to improve the further quality of the paper: 

 

1. At line 39, the authors have mentioned about the refeences 3-8. It is advised to explain the limitation of those paeprs in detials.

2. At line 41-47, the authors explained about the ISDPA design, and DE algorithm but unable to see the complete explanation in rest of the paper.

3. In section 2, the authors prposed ISDPA, but this section more explain about the architecture rahter than the ISDPA design. It is suggested to explain the ISDPA design in detials with steps. 

4. In section 2.2, the authors tried to explain about the optimization that is not enough to justify the novelty of the paper. It looks equaiton 3 is taken from Reference 9. It is highly recommended to explain optimization process in details with equations.

5. It is advided to add more references, and updat the current references (include last 5 years references) as mostly are out dated. 

6. Please include the comparison table to compare your work with other state of art works. 

Moderate editing of English is required.

Reviewer 3 Report

Some comments to the authors:

Row 58.-  "The shared subarray architecture has been utilized in limited scan arrays" include the references.

Row 71.- the j definition is not necessary

Explain the conditions used to obtain the numerical results (anthena that was used, software for simulation)

Include the characteristics of the antennas

The results should be compared with other techniques, a table could be done to contrast the obtained gains.

Increase the number of references, 9 references are not enough for a research article. References Must be of works related to the theme of the last decade

Round 2

Reviewer 2 Report

The authors tried to address all comments but still there is much required to improve the quality of this manuscript. Following are few comments: 

1. The manuscript lack the novelty. 

2. The design of ISDPA and optimization part is not explained propertly. 

3. As mentioned in last comments, mostly references are out dated. The authors did not address that comment properly. 

4. The comparsion table need to address more parameters and add latest state of the art work. 

 

Extensive english language required.
