摘 要:This paper makes a probe into the application of the Kalman filtering method to the data processing of across-fault *** the basis of statistical regression,the mathematic and stochastic models of filtration are established by combining the regression method with Kalman *** the filtering computation,not only the randomness of fault movements but also the time-dependent variation of environmental effects have been taken into *** use of the adaptive filtering method,an estimation of the dynamic noise variance matrix is obtained through *** for one measuring line(leveling line or baseline),two measuring lines(both leveling lines or both baselines)and four measuring lines(two leveling lines and two baselines)are derived and established *** means of these models,the data of across-fault measurements can be processed dynamically in real-time to provide the filtered values of height difference between benchmarks or baseline length at different time
