Abstract: Three-dimensional whole digital simulation is an important research tool for laser tracking and pointing system. In view of the whole laser tracking and pointing simulation system, problems such as projection transform of target’s imaging, relation of imaging and tracking, control process’s simulation of the existing methods are studied for improving accuracy. A tracking and pointing simulation technology based on a kind of imaging series is discussed, and the kind of imaging series has big viewports and considers the effect of atmosphere transfer. Characteristics of accuracy analysis in simulation system are also illustrated. In a simulation scene, two methods are designed, which are named vertex-of-head tracking and pointing method and two-point-acquiring tracking and pointing method.
