Recall tracing can be automatically switched to after temporarily losing target, and difference control is gone back to automatically after the recapture target of optronic tracker 7
The autotrack mode of system.
（2）, guiding tracking working method
Guiding tracking working method mainly completes the capture to target.Because optronic tracker 7 is more tired to target independent acquisition
Difficulty, therefore need the search radar 1 of its exterior to guide it, target is entered in the visual field of optronic tracker 7, then switch
For from motion tracking working method.In low profile photovoltaic tracking system, including search radar guiding and tracking radar guide two kinds of sides
Formula, wherein, tracking radar guiding priority is higher than search radar.
（3）, manual manipulation working method
Manual manipulation working method can manually be drawn under conditions of without exterior guiding equipment to low profile photovoltaic tracking system
Lead, target is tracked down and arrested by the TV tracker 7 of big visual field by manipulator, and control servo-actuated turntable 5 to rotate by joystick, make
Target enters in the visual field of TV tracker 7, then switches to from motion tracking working method.
