IR imaging simulation is an important way to design and assess the IR missile, and the key of simulation is the generation of IR image. The generation of IR image is worthful in military and economy. This Paper simulates the IR image of warship with the computer technology and theoretical analysis. Being constructed with 3DS software, the geometric model of warship is divided into facets in according to the infrared characteristic which is analyzed in various environments and moving states. Based on infrared physics and heat transfer, radiation and convection and conduction are computed respectively for each facet, and the equation in steady state is obtained. The full infrared model of warship is built, which includes the radiation, convection and conduction between different parts of the warship, and which also includes the radiation, convection of environment. To calculate the radiation exchange, the formula based on view factor is deduced, and the temperature distribution is computed with the formula. Based on the temperature field of the warship, the radiance can be obtained with the temperature in according to the Planck Distribution Law, and IR images of the warship can be generated.
