Simulation of reticle seekers using the generated thermal images

This paper presents an efficient simulation method that generates thermal images and gives tracking results of infra-red (IR) reticle seekers. We first construct an IR model of the target having an internal heat source, and generate thermal images produced by the optical system of the reticle seeker and atmospheric turbulence. Using the generated thermal images, we can simulate IR seekers in various cases including countermeasures such as flares. Simulation results show that our method generates accurate images and the constructed loop is applicable to the study of the development of counter-countermeasures.
