Description

technical field [0001] The invention belongs to the technical field of optoelectronic stabilization platform testing, and in particular relates to an isolation degree testing system and method of an airborne optoelectronic inertial stabilization platform. Background technique [0002] The aerial photoelectric inertial stabilization platform system is an effective means to obtain high-resolution images, and plays an important role in military and civilian fields. The aeronautical optoelectronic inertial stabilization platform is installed between the flight carrier and the optoelectronic load, carrying and stabilizing the optoelectronic load, and is one of the important components of the aeronautical optical imaging system. The use of a stable platform can effectively isolate the impact of the non-ideal attitude motion of the flight carrier and various internal disturbances on the visual axis of the optical imaging system, so that the attitude of the optical imaging system re...
