Establishing jamming effectiveness evaluation system of surface source infrared decoy was the key link of effectiveness evaluation. Considering the occasionality of experimental conditions and the economy of test cost, a simulation system was proposed. Firstly, the mathematical model of aircraft and missile was established, and the motion law and radiation factor were fully considered, and the algorithm optimization model was added. Secondly, the motion diffusion model and infrared image model of infrared decoy were established. The combustion optimization algorithm was used to improve the efficiency of the solution. Finally, the effectiveness evaluation index of interference was selected, and the rationality of the simulation system was verified by example simulation and comparison with the measured data. The simulation results show that the established effectiveness evaluation simulation system is feasible and effective, which is close to the experimental results, and meets the requirements of evaluating the effectiveness of the non-point source decoy jamming.
