The MAP Track Fusion Algorithm of Asynchronous Multi-sensor
Qin Chao-ying · Journal of Qingdao University · 2007
In the multi-sensor track systems,communication delays usually exist between sensor platform and track fusion center due to the different sampling rates.So the local estimation of every sensor doesn't arrive at the fusion center at the same time.The fusion center should fuse those asynchronous correlated tracks in order to improve track performance,So the MAP fusion algorithm of asynchronous multi-sensor systems with feedback is presented based on the asynchronous multi-sensor.As an example,It is shown that the MAP fusion of synchronous multi-sensor is a special case of this new algorithm.The simulation results show that the algorithm is effective.
