The research on the infrared radiation with regard to the trail flame of aircraft is important for infrared early-warning and infrared guidance. This paper carries an in-depth study on the infrared characteristic of the high temperature trail flame, quantificational analyzes the model of the trail flame’s airflow field distribution and the calculation of the infrared radiation, does the research for the theory of particle system and the process of the imaging created. At the end, a new method of plane trail flame infrared simulation based on Vega and particle system has been proposed, at the same time analyzed the experimental flow and obtained the experimental result. The result of the experiment shows that the method proposed by this paper is simple on arithmetic and witch also has good fidelity.
