Abstract Optical dynamic target was one of the crucial equipments to test photoelectric theodolite indoor. To test the capability of simulating space-flying objective of a new-type optical dynamic target, its measuring performance was evaluated and its structural advantages were validated. The usual target's traces were simulated by Matlab, and multiple forms of space flying targets were calculated and simulated. The changing curves of the parameters of targets in simulating space target process, including changing curve of angle and error curve of target's angle. Simulating result indicates that velocity and acceleration of targets can match flexibly; the target area that can be simulated is wide; the forms to simulate these targets are multiple and finally this new-type dynamic target is more close to reality. Comparing with conventional targets, it is obviously more innovative and practical. Furthermore, its performance can fulfill the requirements of indoor test on the photoelectric theodolite. By real time compensating error using target's error curve, a theoretic reference is provided to improve the target's accuracy.
