Maximum Likelihood Deconvolution of Beamforming Images with Signal-Dependent Speckle Fluctuations
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe authors have done research on conventional beamforming output with signal-dependent speckle fluctuations from Gaussian random fields using small-aperture linear arrays based on maximum likelihood estimation. The paper is worth publishing however following comments may increase the quality of paper
1. The title of the paper is too long. It should be concise and complete.
2. The literature review in introduction is not up to mark. Additionally, your own research is not defined well. I would suggest elaborating your research work with more clarity.
3. Some key papers are not cited. Key papers on beamforming should be cited in Introduction. I would suggest citing following papers

Journal of Marine Science and Engineering 11 (11), 2184 4. Section 3 describes the basics of MLE. This is available in textbooks. It should be modified by your own research. 5. The novelty and research content are very less throughout the paper. I would highly suggest adding more significant results and do comparison with the previous research, so your work is worth publishing. Comments on the Quality of English LanguageThe quality of English is not up to the mark. There are tremendous typos and grammatical mistakes. I would suggest proofreading the paper several times and enhance the quality of English writing.

Reviewer 2 Report
Comments and Suggestions for Authors1- The title of paper is too long, please revise it to be shorter (I think it must be less than 10 words)
2- Caption of most of Figures are too long, it is look like one complete paragraph, please revise it to be not more than two lines

Reviewer 3 Report
Comments and Suggestions for AuthorsThis paper presents new M-DCV and AM-DCV algorithms to improve traditional beamforming method, and thest algorithms needs less array elements, and this paper used simulation and experiment data to validate the new algorithms.
And there are some questions that the reviewer would like to know the answer,
1. what's the strong scatters in figure 13 and figure 15? the reviewers would like to know what kind of scatters it may be briefly.
2."the AM-DCV algorithm will greatly reduce the computation time", could the authors show the result of AM-DCV in reducing computation time, either use the simulation data or the experiment data.
