Accession number: 20160902015664 Title: Enhanced dynamic error spectrum for estimation performance evaluation in target tracking Authors: Peng, Wei-Shi1, 2 ; Fang, Yang-Wang1 ; Chai, Dong1 Author affiliation: 1School of Aeronautics and Astronautics Engineering, Air Force Engineering University, Xi'an, Shaanxi, China 2School of Equipment Engineering, Armed Police Force Engineering University, Xi'an, Shaanxi, China Corresponding author: Peng, Wei-Shi (peng_weishi@163.com) Source title: Optik Abbreviated source title: Optik Volume: 127 Issue: 8 Issue date: April 1, 2016 Publication year: 2016 Pages: 3943-3949 Language: English ISSN: 00304026 Document type: Journal article (JA) Publisher: Elsevier GmbH Abstract: 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. © 2016 Elsevier GmbH.
