多传感器异步数据融合模型分析

Analysis of Asynchronous Multisensor Data Fusion Model

多传感器异步融合比同步数据融合更为符合实际,不同情形下异步融合模型可以有所不同。在模型噪声和观测噪声互不相关的假设下,建立多个异步数据融合模型并对多个融合模型进行描述,综合分析和比较模型的优缺点;仿真实例说明了各个模型的有效性以及适合应用的环境。

Due to the reasons of sensors in itself and the communication delays,the research of the asynchronous multisensor data fusion problem is more practical than that of synchronous one.In practice,asynchronous multisensor systems are existed abroad,some track fusion algorthms are presented that are valid for different conditions.The measurement noises are supposed to be selfexistent;different sensor data rates and communication delays are used in the simulations.The results illuminate that algorithms is effective;finally paper enumerate their applied circumstance.
