海洋背景的总体辐射受到太阳辐射、天空背景辐射和海洋自身热辐射的影响。在简化的海面辐射模型的基础上，对不同波段、不同天顶角和不同大气环境下太阳辐射的变化进行了比较分析；分析了在各个波段太阳光和大气对天空辐射的影响，着重分析了大气单次散射和多次散射太阳光的情况下天空辐射的变化；分析了大气窗内海洋自身辐射、路径上的辐射和海面反射天空、太阳辐射对红外探测器总体辐射的影响。结果表明，这些因素对海洋背景总体辐射具有较大的影响。

Ocean total radiance is influenced by solar radiance, sky radiance and sea surface radiance. On the basis of studying the simplified ocean radiance model, influences of varied wave band, zenith angle and atmospheric model for solar radiation were analyzed. Influences of solar radiance and atmosphere emission radiance for sky radiance were analyzed in varied wave band. Sky radiance change was taken into account single scattering and multiple scattering of solar while transmitting, respectively. Influences of sea surface radiance, path thermal radiance and sea reflected radiance of sea background and solar for marine total radiance were analyzed. The results showed that these factors had important effects on marine total radiance.
