An Imaging Modeling Simulation Research of Infrared Aero Aero-optical Effect Based on Superposition of Gaussian Mixture Model
By the influence of thermal effect and incoming flow transmission effect from the surface of head head-covering, the high high-speed aircraft equipped with optical imaging guidance system, when flying in the dense and high high-altitude atmosph atmosphere, will cause the rapid degradation of the imaging quality. ere, 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 adop y adopting ting superposition of Gaussian uperposition mixture ixture model, and combining the model with the analysis of odel, flow field and a variety of flight parameters of high high-speed aircraft, Experimental results show that the simulation image is consistent with that of the theoretical analysis.
