The quadrant APD is employed in laser angular tracking system.In this paper,the random tracking errors resulted from various noise sources are analyzed.Mainly discussed are detector noise,sparkle noise,turbulence noise,back scatter noise etc.The effects of them on the tracking system are analyzed,and measures to reduced them are presented as well.
