基于Cox—Munk海面模型,计算了海面对中波红外(3~5μm)的反射率.利用双站散射遮蔽函数对Cox-Munk海面反射率模型进行了修正,数值模拟了反射率随入射角、反射角和风速的变化关系.结果表明,考虑遮蔽效应后.反射率较未考虑遮蔽时的变化更为平缓,且峰值的位置发生变化,峰值明显减小.
Based on the Cox-Munk sea surface model, the reflectance of infrared waves by sea surtace is calculated. Using bistatic scattering radar sheltering function, the Cox-Munk Sea Surface Model is modified, through which the variation of reflectance with incident angle, reflecting angle and wind speed is simulated. The result indicates that with considering sheltering effect, the reflectance is flatter, the peak value diminishes sharply,and its position is also altered.
