Tracking error compensation technology for coherent tracking system

Abstract A method for compensating the tracking boresight error by providing additional jitter for the signal light is proposed. The relationship between jitter angle and system performance is analyzed, which shows the sensitivity attenuation is within 0.1 dB when the angle is within 0.2–1.2 μrad. The optimal mathematical model of output power and compensation angle estimation is established. And the simulation results show the mixing efficiency of the coherent optical communication system is well improved.
