Abstract This paper makes a research on infrared cloud background modeling in order to meet the needs of simulation and verification of infrared detection and guidance adaptability to interference of cloud background environment. Particle system and real image are used to model the geometric characteristics of cloud, and the advantages and disadvantages of the two methods are analyzed. Considering the influence of atmosphere, sun and ground background on cloud radiation characteristics, the radiance calculation is completed. On this basis, the infrared detection device model is established, and finally the cloud background environment simulation image is obtained. The simulation results show that the method can generate cloud background infrared images with rich features， and the infrared characteristic is true and reliable.
