也是 Sci 检索 Enhanced dynamic error spectrum for estimation performance evaluation in target tracking 作者  eng, WS (Peng, Wei-Shi)[ 1,2 ] ; Fang, YW (Fang, Yang-Wang)[ 1 ] ; Chai, D (Chai, Dong)[ 1 ]OPTIK 卷: 127 期: 8 页: 3943-3949 DOI: 10.1016/j.ijleo.2016.01.105 出版年: 2016 查看期刊信息 摘要 The error spectrum is a comprehensive metric for evaluation of estimation performance, which is an aggregation of many incomprehensive measures. However, for dynamic systems, error spectrum is difficult to analyze an estimator's performance since it is a three-dimension graphics for the whole time horizon. Accordingly, dynamic error spectrum was proposed to relieve error spectrum to dynamic systems. The key of dynamic error spectrum is combining error spectrum into one point at a time instant, which unfortunately suffers from information loss. To improve this, a new metric called enhanced dynamic error spectrum is proposed in this paper. Then, both the additive form and the multiplicative form of enhanced dynamic error spectrum are given under different application backgrounds. Finally, the concrete application of the metrics and qualities of the above form are illustrated by numerical examples. The simulation shows that more important information are considered by enhanced dynamic error spectrum and the proposed measure can also be applied easily to dynamic systems. (C) 2016 Elsevier GmbH.
