    Abstract:

    Aero-optical imaging deviation is a kind of optical effect, aiming at a conical aircraft. This paper analyzes the influence of the aircraft on the imaging deviation with the change of altitude and line-of-sight angle. In this paper, the relationships between imaging deviation and altitude as well as line-of-sight angle are analyzed, and the coupling relationship between altitude and line-of-sight angle is studied. We give the imaging deviation results of 5°—75° line-of-sight angle. The analysis shows that when the line-of-sight angle is in the range of 5°—35°, the imaging deviation is more sensitive, while the line-of-sight angle is in the range of 35°—75°, the imaging deviation is relatively flat, and the imaging deviation does not gradually decrease with the increase of line-of-sight angle, but there is a turning point in the middle of 5°—75°. The imaging deviation decreases first and then increases, and the turning point of line-of-sight angle is closely related to height.
