Multi-sensor data fusion based on the eigenvector of relation matrix

A data fusion approach based on eigenvalues and eigenvectors of relation matrix of multi-sensor is proposed. Features of relation matrix are extracted and the information of relation matrix is fully utilized by eigenvalues and eigenvectors of relation matrix. This approach overcomes the problem of influenced by expert experience in threshold settings by the optimal sensor group selected through fusion weight. Finally, the result of digital simulation demonstrates that this approach can be simply calculated with high accuracy and excellent robustness.
