Paper Abstract

By the influence of thermal effect and incoming flow transmission effect from the surface of head-covering, the highspeed aircraft equipped with optical imaging guidance system, when flying in the dense and high-altitude atmosphere, will cause the rapid degradation of the imaging quality. To study the influence of image diffusion, image drift and image dithering caused by optical transmission effect, this paper presents a macroscopic method of simulating the degrade image by adopting superposition of Gaussian mixture model, and combining the model with the analysis of flow field and a variety of flight parameters of high-speed aircraft, Experimental results show that the simulation image is consistent with that of the theoretical analysis.
