Tikhonov Regularization Collocation for Multi-source Gravity Data Fusion Processing

HUANG Motao1,OUYANG Yongzhong1,2,ZHAI Guojun1,DENG Kailiang1,LU Xiuping1,WU Taiqi1 (1.Naval Institute of Hydrographic Surveying and Charting,Tianjin 300061,China; 2.Institute of Surveying and Mapping,Wuhan University,Wuhan 430079,China)  
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.
