Data association is the key to solve multi-sensor multi-target tracking problem, the source of the multi-sensor measurements can be determined after the process of data association. In passive multi-sensor systems, only angular measurements are available, and data association processing is more challenging. To address this issue, a new data association method based on multi-dimensional assignment is proposed in this paper to solve the multi-sensor multi-target tracking problem. Firstly, multi-dimensional assignment process is used to solve the multi-sensor measurement-to-measurement association problem, and the multi-sensor measurements from the same target are collected. The position information of targets is calculated using these associated measurements under the maximum likelihood estimation criterion. Secondly, the association problem between the position maximum likelihood estimates of targets and the multi-target tracks is solved according to the two-dimensional assignment process, the multi-target tracks are updated using the associated position estimates. Monte Carlo simulation results demonstrate the performance of the proposed method and show this method can solve the passive multi-sensor multi-target tracking problem with low calculation load added and high precision.
