The non-uniform flow field around high-speed flying vehicle “bends” the ray and imposes a deviation at the end of the propagation path. This imaging deviation is a kind of aero-optic effect. In this paper, we catalog the factors that influence the deviation into two classes: the vehicle-related factors and the flowfield-related factors. Flow density computation and density–refractive index conversion...
The non-uniform flow field around high-speed flying vehicle “bends” the ray and imposes an imaging deviation on the imaging plane. This deviation seriously affects the airborne imaging applications. In this study, the factors that influence the imaging deviation are cataloged into two classes: the vehicle-related factors and the flow-field-related factors. Flow density computations are discussed....
Aero-optic imaging deviation characterizes the image position displacement on an imaging plane induced by the nonuniform flow field surrounding a high-speed flying vehicle. It is a kind of aero-optic effect that all the airborne imaging systems will encounter. This paper studies the imaging deviation at high altitudes from 40 to 60 km, with a step length of 5 km. CFD computations are completed by...
