Guoqing Qi, Yinya Li, Sheng Andong · 2012
Oriented on asynchronous data in multi-sensor data fusion system, a real-time fusion architecture is put forward, which is in unbiased minimum variance sense. The proposed asynchronous fusion algorithm can solves the measurements sequentially that does not need to preset fusion periods for fusion center to synchronize asynchronous data transmitted from multi sensors. Simulation result has proven the efficiency of the algorithm, and it also illustrates that the algorithm can improve the estimation precision obviously when the target is maneuvering and there is system error in measurement.
