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...

AI Technical Summary

Problems solved by technology

The shortcomings of this system are: it does not consider the modeling of the target background, the modeling of the airborne stabilizing servo control system and the shaking of the carrier platform. When the system is applied to the airborne infrared imaging system, due to the lack of carrier platform simulation modules and machine The simulation module of load stabilization aiming servo control has the disadvantage that the link is incomplete and the signal flow cannot be transmitted.

The disadvantage of this method is that when this method is applied to airborne infrared imaging simulation, it cannot calculate the target miss amount according to the attitude angle of the carrier, realize real-time tracking of the target position, and cannot perform infrared target detection and tracking simulation
