| 摘 要： | 针对最小二乘配置法在融合处理多源重力数据过程中可能出现的病态性问题,特别引入Tikhonov正则化方法,对配置法计算模型进行正则化改造,建立了相应的正则化配置模型。使用EGM2008位模型模拟产生航空重力和海面船测重力数据进行了融合处理仿真实验,实际验证了正则化处理方法的有效性。

| Abstract: | The Tikhonov regularization is introduced into least squares collocation to solve the ill-posed problem in fusion processing of multi-source gravity data. The collocation model is regularized, and a modified regularization collocation model is proposed. Finally,a sea-borne gravity data set and an airborne gravity data set from EGM2008 model are used as a case study to prove the efficiency of regularization collocation. |
