And the frame rough tracking precision of the detected photoelectric tracking system 16 can be calculated according to the residual miss distance of the light spot measured by the detected photoelectric tracking system 16 rough detector.
When the fast reflecting mirror fine tracking precision of the detected photoelectric tracking system 16 is tested, the rough tracking loop and the fine tracking loop of the detected photoelectric tracking system 16 are both opened, and the fast reflecting mirror tracks the target through the light spot miss distance measured by the fine detector.
