Reviewer 2 Report
The manuscript presents the results of experimental studies concerning GNSS multipath problems. Its form is clear, and the research is credibly presented. Moreover, except for some minor language errors needing improvements (I recommend thorough proofreading before further text processing), the study outcomes are understandably and reasonably given. The text has scientific soundness, and the problem is discussed in detail. However, while reading the paper, I spotted some minor shortcomings needing corrections.
# Line 57 - the abbreviation STAP has to be clarified here instead of Line 66.
# Line 67 - probably "mathematical" or "mathematic"; please revise.
# Line 73 - discussing that particular model needs precise justification.
# Line 98, Figure 2 - because the scheme presented is crucial, it needs a more detailed description.
# Figure 4, Lines 136-141 - I recommend placing a more thorough explanation of the problem.
# Equatuion 12, Line 142 - please provide a relevant description of the power parameter.
# Line 186 - please give some information about the equipment used.
# Figures 8 and 10 - please show the appropriate units next to the scalebar.
Should the authors introduce necessary changes into their text, it can proceed for further elaborations toward publishing.

Reviewer 3 Report
Multipath is important phenomenon in positioning in hard observation conditions, especially in urban areas positioning in geodesy, navigation and hydrohraphy. It is important in anti-jamming supporting of GNSS positioning as well. In the article "Suppression of Jammer Multipath in GNSS Antenna Array Receiver" the Authors proposed an equivalent model for interference multipath on the basis of the antenna array model for interference multipath.
The structure of the article is considered and clear. The background and comprehensive review of the problem's literature were presented.
In the main part of the manuscript, array and jammer multipath models have been presented mathematically. Verification for equivalent model, impact of multipath on anti-jamming space only processing with simulatins of SOP and STAP have been presented in graphic form. Discussion and conclusions, on the basis of the research, are comprehensive and clear.
Some well known parts of the manuscript can be deleted because of they are in cited references: i.e. Fig. 1b with equations 1-4
Abbreviations should be efined at the first mention, i.e. GNSS and GPS in line 25
Editoriar mistakes should be corrected:
Line 51: Accuracy in capital letter?
Lines: 76, 84, 90, 116, 146, 152, 157 should begin in small letter as an sequence including the equation.
