Velocity Analysis Using Separated Diffractions for Lunar Penetrating Radar Obtained by Yutu-2 Rover

Round 1

Reviewer 1 Report

General Comments

• Discussion and Conclusion section can be merged and shortened. There seems to be overlap in the content of these sections

Abstract

• Explain why we need to obtain reliable dielectric permittivity model
  • I suggest moving the last line of the abstract to after the sentence on line 13.
• What is meant by migration results? What exactly is migrating? Is it the lunar subsurface materials?
  • Why are the migration results important?

Section 1

• Clearly emphasis the importance of doing velocity analysis. It is not clear to me why this is important, or it's relation to migration results mentioned in abstract
• It will be useful to include a diagram or cartoon depicting the LPR and the lunar environment
  • A cartoon showing the scenario that is being considered in this paper or how the LPR collects the data will be useful to the reader
• Lines 49-75 look like the belong in the Methods section (Section 2)
  • Can also shorten these lines if needed
• Could the authors explain why the strong reflections of the lunar subsurface materials can't be used to build the lunar velocity models? 
  • I assume that the lunar subsurface materials of interest also generate strong reflections. Is that not the case?

Section 2

• Could the authors explain why diffractions have non-planar local slopes?
• Typo in line122: 'flirters' used instead of 'filters'

Reviewer 2 Report

The manuscript entitled “Velocity analysis using separated diffractions for lunar penetrating radar obtained by Yutu-2 rover” reports an interesting analysis of the lunar penetrating radar aboard Yutu-2 rover. The authors clearly describe the method adopted in this study, providing a validation test based on synthetic data. The results are exhaustively presented and are of great interest to the science community. In the attached file, I reported my main comments regarding paragraphs that should be expanded or modified to improve the clarity of the manuscript. I recommend publication of the manuscript after consideration be given to the comments reported in the attached file.
