The paper discusses the process of computer and test aided modeling technique based on correlation method. A certain kind of space remote sensor is used as an example to verify the capability for dynamic model updating. First the correlation analysis of the test modal and simulation modal is made. Then the sensitivity analysis and optmization for key parameters are introduced and finally the results after model updating based on experimental data are given. It is verified that the dynamic model updating of the remote sensor can be realized with the correlation technique.
