Calculation of Routh Sea Surface Reflection

A mathematical expression of surface reflectivity based on Fresnel’s formula and Snell’s law was particularly developed for the rough sea surface, the variation of whose slope in response to the surface wind is determined to the isotropic Gaussian distribution. Subsequently, reflection of rough sea surface in band of 3–5 and 8–12 μm was calculated and extensively analyzed in terms of viewing angle and surface wind. The corresponding results are of great practical significance to reducing the interference to the infrared detection due to reflection of the radiation from sun and sky.
