To realize multi-sensor tracking for maneuvering target state,this paper presents a multi-sensor fusion algorithm based on DSmT and particle filtering.On the basis of observation date which is delivered by multi-sensor and filtered by particle filters.It chooses DSmT as the combining tool.The observation data is transformed into the elements and masses of the frame of discernment,and gets the finally result.Experimental results show that this algorithm can reduce distance error and improve tracking accuracy,and the appropriate computational complexity can satisfy the demand of fusing on-line.
