Abstract: In multiple sensors track fusion environment，aiming at the difference about the number of the sensors detected the target in every moment，this paper designs a model assamble composed by four models，at the same time，applies the tracking gate and curve-fitting theory in this model assamble and filters use counterpart filter which matches the model，and integrates the result into the fusion center eventually.The simulation result shows that the processing about the measurement outlier and one sensor localization problem are solved effectively in this model assamble，and the method about multiple sensors track fusion based on multi-model is availably at the same time.
