Research On Multi-source Navigation Information Fault Tolerant Technology For RBV

As technology advances and manufacturing processes, many new navigationsensors have been developed. Multi-source navigation system and fault-tolerantalgorithms based on redundant information for new sensors became the focus forurgent studying in the military field. Network intelligent match and fault toleranttechnology for multi-source navigation information is a intelligence fusion whichuses sensor networks fusion theory to achieve a consolidation of information frommultiple members during tactical weapons’ high-precision navigation in the future.It is one of the important directions of information fusion technology development.Information intelligent match and fusion process relate to the efficiency of wholenavigation system and the accuracy, reliability and fault tolerance of Informationfusion:1. This paper presents multiple symmetric fading fault-tolerant filter for localsensors group to achieve efficient detection of sensor fault and to improve therobustness of the system, which provides a reasonable criterion for multi-sensoroptimal redundancy and fault-tolerant algorithm.2. This paper studies the global multilevel optimal redundant matching modelfor multiple navigation sensors group and fault-tolerant algorithm with FDIR(FaultDetect/Isolation/Replacement) function which can distribute multi-source sensornavigation data efficiently. For application requirements, this paper also carries outoverlapping information fusion algorithm in case of information update unequalinterval to enhance the feasibility of the model and algorithms.3.As DBN theory, a combination of these proposed models and algorithms formulti-source sensor network intelligent information matches the local faultdetection filter estimates the global FDIR smooth refactoring and navigationinformation selected function package to realize multi-source informationnavigation sensors preferred matching and integration.4. Combining with the application requirements, mathematical simulationanalysis, the principle of the system, algorithm and the feasibility for validation andanalysis, laying the groundwork for the further engineering experiments.
