IPINV: A Two-Dimensional Dipole-Dipole Resistivity Modeling and Inversion Program. User's Guide and Documentation for Rev. 1

摘要

IPINV.REV1 is a batch program that is capable of inverting resistivity data to two-dimensional models for a dipole-dipole array. The forward problem is computed using a transmission surface analogy. IPINV.REV1 is capable of inverting resistivity data to two-dimensional models of arbitrary complexity. The two-dimensional forward modeling routine is based on the transmission surface analogy (Madden, 1972). The inversion algorithm is a linearized least-squares technique. Step-size stabilization is provided by either the Box-Kanemaesu (1972) method or by using a Marquardt step. The program uses log derivatives to increase the rate of convergence.
