Synthetic　aperture　processing　of　radar　sounding　in　ice　is　made　complicated　by　the　curvature　of　the　ice　surface.　In　order　to　tackle　this　issue,　this　study　presents　a　fast　back-projection　(FBP)　ice　exploration　imaging　method　based　on　the　ice-surface　curvature,　aimed　at　reducing　its　effect　on　the　ice-sounding　radar　imaging　results.　The　specific　implementation　steps　of　the　proposed　method　are　applied　in　the　simulation　of　point　targets　and　ice-sounding　radar　data.　Experiments　verify　the　effectiveness　of　the　proposed　algorithm　in　ice　sheet　imaging.　The　experimental　results　demonstrate　that　the　algorithm　can　enhance　imaging　quality　(increase　the　signal-to-noise　ratio　(SNR)　by　approximately　15-20　dB)　while　only　slightly　increasing　time　complexity.
