object carrier
1.Bank card is planted by money different cent is RMB card, foreign currency card; By issue an object different cent gets stuck for the unit (business affairs gets stuck) , the individual gets stuck; By information carrier different cent is magnetism card, chip (IC) card; Credit card is pressed whether to divide to a shot in the locker of hairpin bank deposit write down to borrow card, accurate borrow write down card two kinds.
3.As far as the system observation for accuracy evaluation of carrier rocket is concerned,there may exist different types of observed data and priors.Heterogeneous information means that the different information describing the different characteristics of the same object.Since all of the information is relevant to the same object,the fusion is possible.It is a key problem that how to fuse the heterogeneous information to obtain the better evaluation result.Therefore,the different heterogeneous information and data is thoroughly studied,moreover,the mathematical description for information fusion of different parameter priors and data is constructed in this paper.Based on their relationship between different parameters,indirect prior and observation data is transformed into prior in impact point observation space,which is fused with original prior by weight determined by Maximum entropy rule to obtain the mixed posterior distribution.Therefore,the test results can be given by combining posterior distribution and impact error observed data.Then its application on evaluating guidance systematic error is elaborated as it applies trajectory tracking data,test value of coefficients of guidance instrumentation systematic error,impact point observation data and prior.Especially,the advantage of this method lies in its application in case that guidance instrumentation systematic error may not be computed precisely.Finally a detailed example on evaluation of carrier rocket is given to verify the theory.
