Round 1
Reviewer 1 Report
The paper is dedicated to development and evaluation an algorithm for signal processing of monopulse noise non-coherent wideband helicopter altitude radar. In accordance with the algorithm, a simulation model of pulsed radar with a stochastic probing signal has been developed and the its modeling results are presented in the paper. Mostly, the paper is written well. The results obtained are new, interesting, and valuable for the field. The results are clear, and their discussion is also presented well. Nevertheless, the paper needs some corrections before its publication.
Corrections suggested.
1. The paper should have the following structure (see the journal template): Introduction, Materials and Methods, Results, Discussion, and Conclusions: https://www.mdpi.com/journal/remotesensing/instructions. Please, reorganize the paper to provide the missing sections.
2. Please, substitute ‘Monopuls’ by ‘Monopulse’ in the title of the article.
3. Please, give a more specific Figure 1 caption instead of ‘Geometry of the problem’.
4. Please, use ‘Equation (x)’ instead of ‘(x)’ when referring an equation in the text.
5. Text in section 5. Discussion looks like text for Conclusion. So, it is desirable to substitute section name ‘Discussion’ by ‘Conclusion’, and provide new section ‘Discussion’ describing the obtained results in detail.
6. Reference [4]. Please, correct abbreviation for the journal name is ‘IEEE Instrum. Meas. Mag.’.
7. Reference [23]. Please, correct abbreviation for the journal name is ‘IEEE Trans. Aerosp. Electron. Syst.’.
8. Reference [31]. Please, correct abbreviation for the journal name is ‘IEEE Microw. Wirel. Compon. Lett.’.
9. Reference [35]. Please, correct abbreviation for the journal name is ‘Int. J. Electron. Telecommun.’.
10. Reference [38]. Please, correct abbreviation for the journal name is ‘IEEE Trans. Instrum. Meas.’.
So, the paper needs minor revision.

Reviewer 2 Report
The article develops an algorithm for measuring the flight height of a helicopter or an unmanned aerial vehicle. The article is very well structured, and its clarity is enough. The state of art is enough and the main goal of the work is well defined. The methodology is well explained.
Major comments:
1. Discussion: Try to compare the results with other results of articles of the state of the art.
2. Conclusions: Try to add conclusions or final remarks with the most important results of this work.
Minor comments:
1. Explain better Figure 1 in its description.
2. Explain better Figure 2 in its description.
3. Explain better Figure 4 in its description.

Reviewer 3 Report
It is an exciting investigation where the authors study the narrowband deterministic signals that limit their potential technical characteristics.
I have two remarks.
1. Where are the "Conclusions"?
2. Some significant achievements in this field were done in:
Bashirov, A.E., Eppelbaum, L.V. and Mishne, L.R., 1992. Improving Eötvös corrections by wide-band noise Kalman filtering. Geophysical Journal International, 108, 1, 193-197.
Thomson, S., Fountain, D. and Watts, T., 2007. Airborne Geophysics – Evolution and Revolution. In "Proceedings of Exploration 07: Fifth Decennial International Conference on Mineral Exploration" edited by B. Milkereit, 2007, p. 19-37.
After the revision mentioned above, this MS can be accepted for publication.
