摘要
提出一种不同类型传感器异步量测融合算法,即首先将量测方程线性化,再在融合中心通过建立伪量测方程,得到同步化的量测数据,然后利用一种扩维滤波的思想进行融合处理得到全局估计,最后进行仿真分析。结果表明了该算法的有效性。该算法体现一种并行处理的思想,故数据处理的速度高,特别适用于异步数据的融合处理。
A new method for fusing asynchronous measurement with dissimilar sensors is proposed. At first, linearing measurement ;quation,then,obtaining synchronous data by building pseudo measurement equation at the fusion center, Finally,the parallar filter is utilized to achieve the optimal state estimation. The simulation results show feasibility of the new algorithm developed in this paper,the algorithm reflects a parallel thinking, with high speed of data processing,especially suitable for asynchronous data fusion.
