Abstract: The algebraic reconstruction technique family, including Algebraic Reconstruction Techniques (ART), Multiplicative Algebraic Reconstruction Techniques (MART), Simultaneous Iterative Reconstruction Techniques (SIRT), was studied to reconstruct the three-dimensional distribution of water vapor in this article. The simulation experiment was carried out on Shanghai GPS network. The results show that the algebraic reconstruction technology family can work effectively in water vapor tomography, get rapid convergence, and implement more easily. The range of relaxation factor and the initial value of iteration were also given in the article.
