Interpolation Approach for Velocity Field of Crustal Movement

分析了构建速度场的统计模型和函数模型法,提出利用两种模型逼近原始观测速度的综合逼近法,以减少剩余误差。计算和比较了各种方法,结果显示,综合法优于单独利用统计模型和函数模型法。

The paper analysed the stochastic methods and Functional models which were used to calculated the velocity field and proposed a new interpolation approach integrating two classes of models, for minimizing the residual misfit. It is shown, by comparison between results derived by various models, that the integrated approach is better than the methods based on individual model, either functional or stochastic, for interpolation of velocity field.
