多传感器异步量测融合算法性能比较

Performance Comparison of Several Multi-sensor Asynchronous Measurement Fusion Algorithms

归纳几种多传感器异步量测融合算法,即首先将各传感器异步数据统一到同一时刻,再对该数据进行并行或伪序贯滤波处理。分别采用理论证明和实例仿真分析对各种算法的估计精度、计算量等性能进行了比较。所得结论对实际工程应用中异步量测融合算法的选取有一定的指导意义。

Currently there exist several asynchronous measurement fusion algorithms, namely, firstly strict synchronizing sensors asynchronous data and deal with them with parallel or pseudo-sequential filter. The estimation precision and calculator of these algorithms are compared by theory proving and example emluator analyse in this paper, the conclusions are valuable in practical engineering application.
