Abstract

An ocean surface model for synthetic 3-5micrometers and 8~12micrometers infrared imaging application has been developed which is based on the JONSWAP wave spectrum. First, the slope of sea surface was calculated by the JONSWAP wave spectrum. Next, the emissivity of the sea surface was obtained from the slopes. After that, the geometric relation of sun, sky and facet of sea is used to determine whether the radiance of the sun is reflected by this facet or not, and the radiation at detector is obtained. Later on, the noise of detector was simulated by average method. Finally, 3-5micrometers and 8~12micrometers infrared images of sea background is generated. The texture of 3-5micrometers and 8-12micrometers simulated infrared images is statistically analyzed. The statistics includes temperature histogram, standard deviation analysis. The results show that the texture of 3-5um and 8-12um infrared images is similar in many statistics. But to the images that are derived from the high-reflective ocean surface incurred by the sun, the textures have some differences. The similarities and differences of the textures are explained in theory.
