A Quasi-Quadratic Inverse Scattering Approach to Detect and Localize Metallic Bars within a Dielectric

Round 1

Reviewer 1 Report

A quasi-quadratic inverse scattering approach to detect and localize metallic bars within a dielectric is investigated in this manuscript. The paper is well organized but there are several comments should be addressed.

 

1) The novelty points should be clearly explained and stressed. What are different from reference [21].

2) why quadratic not cubic or quartic, which are more representative for nonlinear?

3) A comparison with published methods should be presented.

4) Only numerical studies are presented, it is better to present some experimental demonstrations.

Reviewer 2 Report

The author mentioned some NDT methods such as microwave and GPR, but no information was given about the application of these methods in the article. The differences of the methods expected to be applied compared to other NDT methods and why they were chosen are not explained. Since the graphs given in figures 5-8 do not have axis information, they do not make sense for the reader. The conclusion is extremely unsatisfactory. It should definitely be expanded. It is recommended to the author to benefit from the following studies in the Introduction section.
