Airborne　SAR　remote　sensing　image　has　the　characteristic　of　large　data　volume　and　computation　burden,　so　the　processing　needs　very　large　computer　memory　and　stronger　computation　ability.　Based　on　the　introduction　of　the　SAR　image　processing　procedure,　this　paper　studies　the　SAR　image　processing　using　computer　parallel　computation　technology.　The　parallel　processing　mechanism　is　based　on　the　parallel　computer　cluster　operation　and　the　large　virtual　shared　memory　technology.　In　the　Client/Server　architecture　based　SAR　image　parallel　system,　agent　based　network　communication　plays　an　important　role　in　the　computer　performance　monitor　and　burden　distribution.　In　the　end,　the　application　of　the　SAR　image　parallel　processing　system　in　the　disaster　monitor　and　assessment　system　is　introduced.　The　application　result　illustrates　the　high　efficiency　of　the　system　and　the　feasibility　of　our　research.
