    In practical application of Radon Transform, we must consider the sampling problem. The Shannon sampling theorem is not suitable in geophysics, because it needs the function considered being band-limited. In this paper, the method of establishing new sampling theorem by wavelet theory is studied. The superiority of this method is that we can select appropriate fundamental space Vo according to the practical demands, and gain mort accurate results.
