Round 1

Reviewer 1 Report (Previous Reviewer 1)

The reviewer noticed that careful revisions were made accroding to the comments in this version，I have no further question. 

Author Response

Thank you for your careful reading and good comments on our manuscript.

Reviewer 2 Report (New Reviewer)

The author presents a discussion on antenna array optimization for mirrored aperture synthesis based on dual-polarization. Following are my concerns:

1) why the author have used blue hyperlinks throughout the manuscript is this a revised version?

2) Please check for correctness equations 5 and 6.

3) what is the y-axis in Fig 5, 7,8,10

Thank you very much for your careful reading and good advice. Please refer to the attachment for details

This manuscript is a resubmission of an earlier submission. The following is a list of the peer review reports and author responses from that submission.

Round 1

Reviewer 1 Report

In this manuscript, a antenna array optimization method based on mirrored aperture synthesis is proposed, and the optimization models are simulated to verify the effectiveness of the optimization method. However, the technical innovation of this manuscript is insufficient, so it is not suitable for publication in this journal. My comments and questions are as below:

1.     The title of this manuscript seems to be incomplete, the reviewer suggests that the authors should revise or supplement the title of this manuscript.

2.     What is the technical innovation of this manuscript? Can the optimization method reduce the dimension of the antenna array, or can it be applied to the radar system of the new system?

3.     In Figure 11, the authors use the simulated brightness temperature image to verify the correctness of the optimization method. The reviewer recommends using the radiation pattern of the antenna array instead of the brightness temperature image to validate the optimization method.

4.     The optimization method proposed in this manuscript lacks experimental verification.

5.     In section 2, the incidence and reflection of electromagnetic waves on the surface of ideal conductor are basic knowledge in textbooks, and there is no need to write them in papers.

Reviewer 2 Report

Thanks for working on the antenna array optimization technique. My comments on this work are as follows:

(1) Since this complete work is based on simulations so we cannot judge whether the particular technique will work in real life or not. Validation is one of the important and necessary steps for antenna engineers.

 

(2) Literature is not covered completely and the recent state of the art is missing. Please check the literature.

 

(3) The model taken for the polarization scheme is only taken for a single scenario.

 

(4) Figure 1 is taken from the basic electromagnetic book and needs to be referenced properly. Maybe sadiku book or Robert paknys book.

 

(5) What about diffraction in the proposed technique?

 

(6) Equations did not introduce the frequency selective losses.

 

(7) Experimental demonstration is a must to see the losses associated with practical setup.

Reviewer 3 Report

In general I found this paper worth publishing, after following remarks are properly addressed.

 

1. You presented only benefits of your solution, but not the shortcomings.

The most obvious issue is increased complexity of the system utilizing your solution. Dual polarization antennas are more complex to realize and are heavier that single polarization antennas. Both factors are more than important in satellite design. Not to mention increased cost of the DPA solution, both for the production of the antenna and for launching it into orbit. In ordered to accept this paper, I am requiring a section which covers issues mentioned above.

2. Extensive editing of English language is required.

Even the basic terminology used in this paper is questionable. For example, "parallel" polarization should be "horizontal" polarization. Grammar used in this paper is quite bad. 

 

I am looking forward for the revised paper.

Best regards,

Reviewer
