GM(1,1)灰色模型在目标跟踪中的分析和改进

Analysis and Improvement of GM(1,1) Used in Target Tracking

分析GM(1,1)灰色模型应用于目标跟踪的性能,指出其为受限的变加速模型,提出了速度模型的概念,并指出模型精度的受限的原因,给出相应的改进方法,最后通过仿真说明了该方法的有效性。

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.
