This　paper　presents　the　ice　thickness,　fine　resolution　internal　reflecting　horizons　(IRHs),　and　distinct　bottom　topography　measurements　of　Chinese　Kunlun　Station　and　Grove　Mountains,　Antarctica,　derived　from　sounding　these　glaciers　with　a　high-resolution　radar.　To　enable　the　development　of　next-generation　ice-sheet　models,　we　need　information　on　IRHs,　bottom　topography,　and　basal　conditions.　To　this　end,　we　performed　measurements　with　the　progressively　improved　ice-sounding　radar　system,　currently　known　as　the　high-resolution　ice-sounding　radar　developed　by　the　Key　Laboratory　of　Electromagnetic　Radiation　and　Sensing　Technology　of　Institute　of　Electronics,　Chinese　Academy　of　Sciences,　Beijing,　China.　We　processed　the　collected　data　using　focused　synthetic　aperture　radar　(SAR)　algorithm　named　the　modified　range　migration　algorithm　using　curvelets　and　the　modified　nonlinear　chirp　scaling　algorithm　to　improve　radar　sensitivity　and　reduce　along-track　surface　clutter.　Representative　results　from　selected　transects　indicate　that　we　successfully　sounded　3-km-thick　ice　with　a　fine　resolution　of　0.75　m.　In　this　paper,　we　provide　a　brief　description　of　the　radar　system,　discuss　the　focused　SAR　processing　algorithms,　and　provide　sample　results　to　demonstrate　the　successful　sounding　of　the　ice　sheet　in　Antarctica.
