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.

摘要： 针对某些多源航迹融合应用系统中通信带宽有限、通信质量欠佳等现实条件致使网络传输数据少、通信延时无序的问题，提出一种基于部分可利用局部估计同步化及最少信息自适应权值估计的异步航迹融合技术。该技术克服了现有方法中对局部估计质量等信息的依赖，并能避免部分传输数据延时过大对融合实时性能造成的损失。通过一个仿真例子验证了方法在实际应用尤其是通信受限的多源融合系统中具有较强的实用性。
