Short summary

Seismic imaging of subglacial lakes is affected by multiple reflections, guided waves, and source-side ghost effects, which dominate seismic records and complicate imaging. Using wavefield simulations under varied geological scenarios and real data analysis, this study clarifies how these effects arise and tests processing methods to reduce them.
