| Abstract: | Targeting at the new type data called gravity gradient, the basic formulae and equations of the global line mass model and harmonic analysis are derived. The line mass models based on radius real component, horizontal complex component and full tensor are studied,so are the least squares solutions. The harmonic analysis formulae of line mass models are shown completely, which have various advantages such as eliminating the disperse errors and dealing with multi types data compared with point mass harmonic analysis. The line mass method is better than the point mass method as the former is with consideration of different depths and with various frequencies. Finally, the availability and validity are proved through simulation experiments. |
