| Abstract: | For the research on regional crustal movement, collocation model is always used to estimate the points which need attention without observation.However,because of its tendency characteristics of function model and its active characteristics of statistic model, accurate covariance matrix of the model is hard to be determined.This paper has analyzed and compared some popular covariance function, then brought up a new collocation model based on displacement principle. The new model can build up different collocation model aiming at different points, thus many avoid the accuracy loss of using experiential covariance function. The accuracy of the new model is apparently higher than normal collocation model through special verification. |
