Research on Kalman Filtering Algorithm for Deformation Information Series of Similar Single-Difference Model

摘要

Using similar single-difference methodology(SSDM) to solve the deformation values of the monitoring points, there is unstability of the deformation information series, at sometimes. In order to overcome this shortcoming, Kalman filtering algorithm for this series is established, and its correctness and validity are verified with the test data obtained on the movable platform in plane. The results show that Kalman filtering can improve the correctness, reliability and stability of the deformation information series.
