【Abstract】 Analyzes the applicability of GM(1,1) used in target tracking and point out that it is a non-uniformly accelerating model constrained.Puts forward the conception of velocity model in order to improve the performance of GM(1,1) during a long-period detection. On the basis of the analysis of GM(1,1), this paper explains the reason why the performance of GM(1,1) is constrained and put forward a method to improve it. Computer simulation shows that the method is effective.更多还原
