Abstract: For certain multi-source track fusion application system with short network data transmission and out-of-sequence communication delay resulted from limited bandwidth and poor communication quality, a new asynchronous track fusion technology is put forward based on synchronization with partial available local estimations and adaptive weight estimation with minimum information. This technology overcomes the reliance on the information of local estimation quality found in the existing methods as well as be capable of avoiding real-time performance loss brought about by overlarge delay of certain transmitted data. In the end, a simulation is carried out which validates the strong practicability of this method in practical applications especially in multi-source fusion system with limited communication.

Key words: limited communication, partial synchronization, adaptive weight, asynchronous fusion
