Infrared image simulation plays an important role in many fields. This paper presents a method for
dynamic infrared image simulation under various natural conditions. Firstly, we analyze the infrared
imaging rationale, considering various affected factors of temperature, radiance filed and atmospheric
attenuation based on the heat transfer equation. Secondly, we present a reasonable simulation
procedure based on the Vega Application Interface (API). Especially, a hybrid simulation idea is put
forward and an improved strategy for different objects is carried out. The performance of this approach
is evaluated by simulating two kinds of targets. Results show that the method proposed is valid
compared with the real images under the same condition. In addition, this approach has relatively low
calculation complexity but high fidelity, and satisfies the requirement of real time.
