A Smart Multi-Rate Data Fusion Method for Displacement Reconstruction of Beam Structures
Round 1
Reviewer 1 Report
The authors proposed a multi-rate data fusion technique for displacement reconstruction of beam structures. The manuscript is well-written and adequately presented. The reviewer has the following concerns:
- The authors mention the reconstruction error is 5% for the noise level of 5dB. Did the authors check the proposed method for noise levels less than 5dB? The trend shows the higher the signal-to-noise ratio, the less error. Clarify?
- Why did the authors choose specifically SSI for mode shapes?
- The authors should add disadvantages of the proposed method too to improve the readability of the article.
- Did the authors validate the proposed method on any real-life structure? Why or Why not?

Reviewer 2 Report
This manuscript presents a novel method for dynamic displacement reconstruction of beam structures in a real-time manner. The effectiveness of the method was demonstrated with both numerical and experimental tests with less than 5% error.
The manuscript is very well-written and presented. It can be accepted for publication by Sensors after considering the following minor comments:
- As this study aimed to achieve online reconstruction, can you elaborate on the online real-time performance for both numerical and experimental validations?
- Line 138, full term of abbreviations such as SSI here, should be given when first appear.
- Line 247, can you be more specific about what "complex" excitation pattern was applied?
