Comprehensive pulsar time analysis method and system based on iterative filtering

The invention relates to the technical field of pulsar time, in particular to a comprehensive pulsar time analysis method and system based on iterative filtering, and the method comprises the steps: combining the timing residual errors of pulsar in pairs according to a combination rule to form a plurality of pulsar timing residual error master-slave groups, and carrying out the iterative filtering through a Vondrak-Ceepk filtering algorithm to obtain corresponding filtering timing residual errors; after each round of iterative filtering, the filtering timing residuals output in the previous round of iterative filtering are combined pairwise according to a combination rule to obtain updated pulsar timing residual master-slave groups, and the updated pulsar timing residual master-slave groups are used as the input of the next round of iterative filtering until the total number of filtering iterations is reached, so that the comprehensive pulsar time stability is obtained. Compared with an original single pulsar
