A shallow water interface interference separation and sound field reconstruction method based on the equivalent source method was proposed. The combination of the ray acoustic virtual source method with the equivalent source method can effectively separate the impact of interface reflected sound in shallow water conditions, and accurately reconstruct the radiated sound field of structural sound sources. The virtual source method model was briefly described in this paper, the basic principle and algorithm implementation process of the interference stripping equivalent source method were given, the impact of different frequencies and holographic surface configurations on the algorithm was illustrated through simulation, and the advantages and applicability of this method compared to conventional equivalent source methods were summarized.
