| Zusammenfassung: | The invention relates to a centralized fusion robust filtering method, which solves the technical problem of low accuracy, and comprises the following steps: 1, detecting the line interference degree of an observation value of a local filter, and extracting a filtering observation value; presetting interference degree tolerance of the central subunits, wherein the interference degree tolerance of each central subunit is different; 2, defining that the interference degree is greater than the interference tolerance if the interference unweighted value is 1, and representing that the interference degree is less than or equal to the interference tolerance if the interference unweighted value is 0; performing weighted calculation on an interference unweighted value, if the calculated value exceeds a threshold value, executing the step 4, otherwise, executing the step 5; step 3, enabling the central subunit to reject interference information of the observed quantity to complete reconstruction of the observed quanti |
