Variable Doppler Starting Point Keystone Transform for Radar Maneuvering Target Detection

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

 

The major issue I have with this work is its lack  use of any real radar data. This puts in doubt the soundness of the research method used in an engineering field and its usefulness for the readers of the Journal that it has been submitted to. With the  availability of low cost hardware to generate one’s own data and large amount of real radar data available by the others on online or otherwise, it is not accepted to just use simulated data. Moreover even in simulation a physics -based simulation tool must be used. 

I recommend that the authors test their method on real data and resubmit.

Reviewer 2 Report

Comments and Suggestions for Authors

The VDSPKT is proposed by the authors to address the RM problem in the long-time integration of moving targets, based on KT. The authors mainly demonstrated the performance of the proposed method in addressing two issues related to HBVE and NDFR. I believe that the research arrangement of this paper is reasonable, with sufficient theoretical reasoning and experimental verification, supporting the research conclusions. Overall, the paper is good, but there are some minor issues that need to be addressed.

1. The Introduction section could be more enriched by citing more references.

2. There are minor edits needed in the English language. For example, lines 120-127, 262-271 and 360-369 could be clearer and more fluent.

3. The description of the experimental results could be more comprehensive.

4. The explanation of  in formula (1) is missing.

5. The format of heading 2.3.1 needs to be modified.

6. The format of the legends in Figures 7 and 8 for the same method should be consistent.

Reviewer 3 Report

Comments and Suggestions for Authors

This paper proposed a variable doppler starting point Keystone transform for radar maneuvering target detection. The topic is interesting and this paper is well written. Some comments are given below:

1. All abbreviations should first be accompanied by their full names, such as ISAR.

2. The image quality is not high, and it's a bit blurry, especially the 2D graph.

3. One of the main issues in this paper is the lack of certain technical details, making many formulas difficult to understand how they were derived. It is suggested that the authors should provide additional derivations to complete the process. 

4. Currently, multichannel radar systems are becoming increasingly common. Can the method proposed in this paper be applied to these systems? such as: “Multichannel adaptive signal detection: Basic theory and literature review,” Science China: Information Sciences, vol. 65, 2022.

Dear Reviewer 1,

I hope this message finds you well.

I would like to extend my sincere gratitude for your valuable suggestions. The references you provided are highly relevant to the theme of our paper and significantly enhance the research background. Consequently, we have incorporated the first two references you suggested as citations [12] and [13] in our manuscript.

I would also like to clarify that the third reference you provided is our own preprint, which was published on the Preprints.org platform upon the journal's suggestion during our initial submission. As it contains the same content as our current manuscript, we have not included it as a separate citation in the article.

Thank you once again for your insightful feedback and for contributing to the improvement of our work.

Best regards,

Wei Jia
