The combination and divergence of multi-target tracks are very common in the engineering practice

which make it more difficult for the track fusion.In this paper

a novel track fusion method with an adaptive sliding mean window is proposed.Meanwhile

the adaptive associated matrix of proposed method is also given here.The proposed method could adaptively measure the effect of history track on the current track for the multi-target

thus judge the track combination and divergence

effectively and accurately.Furthermore

the simulations are performed with two sensors and two targets

have also shown that the proposed method is valid and stable for the track fusion

especially to the track combination and divergence.
