摘　　要：测量离水辐亮度的水面之上测量方法中最大的不确定性因素是太阳耀斑的污染和海面反射率的估算。文章根据Cox和M unk研究结果,利用大量随机数模拟海面波浪倾斜,估算不同仪器观测方向与风矢量几何以及不同仪器视场角下的海面反射率,并估算出不同太阳天顶角及相对风矢量方位角的太阳耀斑基本分布。In the above-water method to measure water leaving radiance, the main uncertain factors are contamination of sun glint and estimation of sea surface reflection. According to Cox and Munk＇s research, this paper estimates sea surface reflection under different geometry of view and wind vector and different field of view , and the distribution of sun glint under different sun zenith and relative azimuth to wind vector by using large random data to simulate slope of sea wave.
