With the development of researches on out-of-sequence measurement problem, attentions have been given to the out-of-sequence track (OOST) fusion problem existed in distributed system.Aiming at the out-of-sequence track fusion problem in distributed system with feedback, we put forward a fusion algorithm based on recursive fusion NALE mechanism.In fusion center, the local estimation arrived out-of-sequence was processed recursively.And at the end of global fusion period, the global estimation was fed back to the local processor.Theoretical and simulation results indicate that the new algorithm can effectively deal with OOST problem, and can improve the stability and real-time performance of the system.
