THE SIMULATION OF INFRARED IMAGING OF THE SHIP

An IR theoretical model of the ship was presented The effect of the en vironment on the object, and the interaction between different parts o f the object were investigated. The thermal model includes solar heati ng, sea/sky radiation, sea/air convection, the conduction between diff erent parts of the ship and the surface radiation (which ac counts for multiple diffuse reflections); the radiation and convection of the ho ld were also included. Based on the Monte-Carlo method, the quasi-rand om number was introduced to the calculation of radiant heat exchange b etween non-diffuse-gray surface of complex geometrical structure. The fluid, temperature field and IR emission of hot gas in the funnel were investigated and calculated. For a ship, the 3D surface geometry a ta rget was defined, the temperature and IR emission field were calculate d, and the simulated LR thermal image was presented.
