It can jam the approaching infrared imaging guided missile by simulating the infrared signatures of the fighter to be protected. Firstly, the mechanism of surface-type infrared decoy for jamming infrared imaging guided missile was analyzed. Secondly, the radiation and moving models of surface-type infrared decoy were built. Then, the change rules of the surface-type infrared decoy's position, area and gray-scale were analyzed. The infrared images of the surface-type infrared decoy were generated. Finally, regarding the jamming success probability as the jamming effect evaluation criterion of surface-type infrared decoy, the jamming success probability in different distances and different quantities were calculated, and the simulation results were analyzed. The simulation results show that the surface-type infrared decoy can realistically simulate the spectral radiation distribution characteristic of fighter, which can effectively jam the infrared imaging guided missile and greatly improve the battlefield survivability of fighter.
