Box 14155- 6466, Tehran, Iran and Center of Excellence in Geomatics Engineering and Disaster Management, Survey Engineering Department, University of Tehran Journal Article 2006 01 02 The least-square minimization approaches for determination of depth, shape and amplitude coefficient expressed by Abdolrahman et al. (2001) for sphere and horizontal cylinder is used for rectangular prisms as synthetic models with and without random noises. The method is also applied for real sources producing micro-gravity data .The capability of the method is tested and discussed in this paper.
