为了提高多传感器数据融合中的精度,本文提出了基于误差估计的异步融合处理方法 ,该方法将传感器观测值与融合航迹的预测值直接融合,同时保证多传感器融合结果的数据率和融合之后的精度。本文进行了对比仿真实验,结果表明该方法在直线和转弯条件下的估计精度都比同步方法更高。

To improve the precision of data fusion in multi-sender network, this article proposed an asynchronous fusion method based on error estimation. In this method, the observations of every sensor calculated with fusion tracks directly, assuring data rate and precision simultaneously. In this article, comparison between asynchronous and synchronous methods is made, and indicates that the result of asynchronous method are better than the other one.
