Experimental Investigation into the Active Narrowband Reshaping of a Ship Model’s Acoustic Signature

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Would be more insightful to readers if intermediate outputs from the workflow on adaptive digital processing implementation for both the ANE/ASI can be shared either in the (Provide snippets) main manuscript/Appendix. Explanations behind use of equations/variables can be made clearer by mentioning impact of certain important terms in the equations.

Reviewer 2 Report

Comments and Suggestions for Authors

1. While the paper addresses control efforts, it does not thoroughly explore the robustness or stability characteristics of the adaptive algorithm. Important aspects such as convergence behavior, resilience to modeling errors, and sensitivity to phase mismatches are left unexamined and warrant further analysis.

2. The current experimental framework is based on simplified, deterministic inputs. To enhance the applicability of the study, the authors should consider discussing how the control system would respond in more complex, real-world conditions involving stochastic disturbances and transient, broadband excitations. Alternatively, suggesting directions for future research in this area would strengthen the manuscript.

3. The study would benefit from the inclusion of quantitative measures of variability to reinforce the reliability of the findings. Incorporating statistical indicators, such as standard deviations, confidence intervals, or error bars based on repeated measurements, would increase the scientific rigor and credibility of the results.

4. The ship model used in the study omits several critical noise sources typically present in full-scale vessels. These include factors such as propeller cavitation, flow-induced boundary layer noise, and hydrodynamic hull interactions. A brief analysis of how the absence of these elements may affect the generalizability of the results to operational naval platforms would be a valuable addition.
