Abstract In order to overcome the influence of sensor system error and random measurement error in correlation process, this paper presents a twodimensional track correlation method. The method establish functional relation to explain the influence of sensor system error and random measurement error on position difference between tracks which are formed by one target in different sensors. The first threshold is established based on the range of position difference. And the second threshold is formed based on the range of variance for position difference of a sequence in continuous moments. Simulation results show that the method has higher correct correlation rate than traditional double-threshold correlation.
