An integrated recognition algorithm based on DSm theory is presented to solve target recognition problems of digital multi-purpose radar. First, various recognition results were placed in a unified frame of discernment and the classic DSm rule was applied to combine them. Then the Proportional Conflict Redistribution (PCR) rule was used to redistribute the combination results. Finally, the decision rule based on generalized basic belief assignment (GBBA) was adopted. The simulation results show that this method can avoid information loss caused by the hierarchical recognition structure, and more abundant target information is included in the fusion results.
