Focus on the tracking target for detection indoor,the angle peak characteristics are analyzed based on uniform circular motion and the void-zone is proposed.The sine angular trajectory is used to transform the actual target into the infield,which improves the value adaptability of the peak angular acceleration to velocity and accommodates the mobility condition of photoelectric turntable.Fight trajectory is generated by atri-axial optical target and the tracking experiment is carried out by theodolite to realize the physical simulation of trajectory,which provides powerful conditions for evaluating the tracking performance of photoelectric turntable under the mobility index.
