Photoelectric detection system and method for GEO satellite omnidirectional alarm

A photoelectric detection system and a photoelectric detection method for GEO satellite omnidirectional alarm belong to the technical field of omnidirectional alarm, and a GEO satellite is equivalentto a cuboid, four rotary tables are respectively arranged on four edges, perpendicular to a GEO orbit plane, of the GEO satellite, each rotary table is provided with a visible light camera, and the visible light cameras are respectively connected with the GEO satellite. The other two cameras are directly mounted on two surfaces parallel to the GEO track surface; the four rotary tables control thefour visible light cameras in the GEO orbital plane to avoid direct solar radiation according to the position and angle relation between the GEO satellite and the sun, it is guaranteed that the four rotary tables are not shielded by the satellite, and meanwhile the space area outside the sun avoidance angle is covered; at least one solar blind ultraviolet camera is installed on the GEO satellite,and the field of view of th
