• Abstract : the reflective characteristics of sea and sky background radiation , which have important effect on the infrared signature from flight vehicle above sea , are studied in the paper . the statistical distribution of wave facet directions is discussed , the effects of randomly riging and falling sea wave on the sea surface radiation and on the sun light reflection are also discussed . calculation methods of irradiance from sea surface radiation and reflected sun light on observation point are derived in the paper . finally a computation example is given , which shows the sea and sky background radiation has important effect on infrared characteristic especially in the front area of a flight vehicle
  文摘:研究了对近海飞行体的红外特性有重要影响的海空背景辐射的反射特性.讨论了波浪面起伏随机规律，随机起伏对海面自身辐射及对阳光反射的影响，推演了此种随机起伏波浪面的自身辐射及反射的阳光在观测点形成的辐照度的计算方法.给出的算例结果表明，海空背景对飞行体的红外特性尤其对其前半球的红外特性有重要的意义
