Example Embodiment
[0017] Refer to figure 1 . According to the present invention, in the radio frequency / laser cooperative fast acquisition tracking alignment system, the acquisition tracking alignment is divided into radio frequency tracking and laser tracking; in the radio frequency tracking stage, the beam pointing controller detects the radio frequency omnidirectional beam and the radio frequency directional beam respectively. Information, extract the alignment error between the target pointing and the current actual pointing as the feedback amount, control the radio frequency directional beam and the laser beam pointing, and quickly find and capture the laser beam in the entire airspace with the aid of the radio frequency beam, and then switch to laser tracking; In the laser tracking stage, the beam pointing controller uses the beam information detected by the optical coarse field of view and the fine field of view respectively to extract the alignment error between the target pointing and th...
