Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: the authors of manuscript "An Efficient Real-Time Signal Processing Method for Satellite Laser Ranging" provided a methor to a kind of real-time SLR data processing method, and solved the challenges brought by the weak echo signal and high noise level of the high-orbit satellite clock. The research method is highly innovative, the result improvement is significant, and the research content conforms to the scope of PLOS ONE.

Reviewer #2: This authors proposed a new multi-stage filtering algorithm to improve signal processing for satellite laser ranging (SLR). The authors claim that their method addresses challenges related to weak echo signals and high noise levels, especially for medium- and high-orbit satellites. The proposed algorithm builds on the Graz filtering method and incorporates a histogram-based secondary filtering technique and least squares fitting.

The proposed algorithm shows promise in enhancing the identification of valid signals from high-orbit satellites. The authors have also clearly explained how the multiple filtering stages improve performance compared to traditional methods. This research also addresses important issues in real-time satellite tracking and space debris detection.

I recommend this paper publication after the authors address the following concerns.

1. What challenges were encountered when testing the algorithm with real-world data, and how were they addressed?

2. While the paper acknowledges limitations regarding threshold adaptability and the reliance on operator experience, it would benefit from a more in-depth exploration of how these limitations might impact practical applications in various environments.

3. What criteria were used to determine the optimal values for the parameters used in your filtering algorithm?

4. The paper makes valuable comparisons with traditional algorithms; it would be significantly enhanced by incorporating a wider range of diverse filtering techniques for evaluation.

5. How does the algorithm perform with dynamic signals that may change rapidly during observations? Is it capable of adapting to sudden changes in signal strength or frequency?
