Abstract:In this paper, an infrared image simulation system for sky and sea background is designed. Sky background and solar infrared radiation are calculated using atmospheric transmission model software Modtran. 2D sea surface geometric model is generated based on JONSWAP sea spectrum. Based on heat radiation theory and optical scattering theories on rough surface, infrared radiation and scatter for background radiation from sea and target are calculated, respectively. Infrared simulation image for sky and sea background can be obtained eventually. It is significant for the studies of the sea-sky background Infrared radiation character and the algorithm of target identification.
Keywords:infrared images simulation  sea-sky background radiatiom rough surface~ optical scattering
