As a part of the feasibility study of the satellite-borne rain radar for the Tropical Rainfall Measuring Mission (TRMM), quantitative estimation of the effects of surface clutter on rain measurement is made for clutter coming from the sea surface. The sea clutter interference discussed includes that entering through the pulse compression range sidelobe and that through the antenna sidelobe. Calculations are made for the proposed dual frequency radar operating at 13.8 and 24.15 GHz. It is found that sea clutter received through the range sidelobe can considerably interfere with rainfall measurements up to several mm/h at 13.8 GHz, while interference through the antenna sidelobe is not so significant, only affecting the measurements of very weak rainfall below several tenths of mm/h.
