| 摘 要： | 为确定联合反演模型中的相对权比,提出根据数据先验信息对相对权比进行一定约束,并将相对权比同其他模型参数一并作为未知参数参与反演的方法。数值实验表明,当先验信息可靠时,运用该方法可以获得较好的结果。

| Abstract: | How to choose the relative weight ratio λ is an important problem that deserves to be studied in inversion models when using more than two physical measurements, including the geodetic displacements to implement the joint inversion. The idea of computing the λ with it and other inversion parameters as the parameters to be inverted is put forward, and the inversion model is derived in detail. Through simulated data and the solution, the effectiveness and feasibility of the method above is proven. |
