Description

technical field [0001] The invention relates to the field of photoelectric imaging, in particular to a full-link and full-process simulation system and method of an airborne infrared stabilization system. Background technique [0002] The airborne infrared stabilization system is mounted on the aircraft, and the attitude change and vibration of the carrier aircraft will cause the instability of the boresight pointing, which will have a significant impact on the clear imaging of the observation equipment of the airborne infrared stabilization system. In order to overcome these effects, a visual axis stabilization subsystem must be established to isolate the visual axis of the optical sensor in the system from the movement and vibration of the carrier platform, so that the visual axis is stabilized in a fixed inertial space direction. At the same time, in order to be able to track and observe the observed target in real time, it is required that the airborne infrared stabiliza...
