M Shademan; A.R Arab-Amiri; H Kheyrollahi; D Rajabi

Volume 24, Issue 95 , June 2015, , Pages 197-202

http://dx.doi.org/10.22071/gsj.2015.42192

Abstract
  Frequency Domain Electromagnetic surveys are being used for various applications like mineral and water exploration, environmental hazards and buried human-made materials because of its resolution and fast acquisition for low depth targets. Resistivity and its depth for each frequency could be calculated ...  Read More

A.R. Arab-Amiri; A. Moradzadeh; D. Rajabi; B. Siemon; N. Fathianpour

Volume 19, Issue 75 , January 2010, , Pages 115-118

http://dx.doi.org/10.22071/gsj.2010.55453

Abstract
  It is about 30 years that Helicopter electromagnetic (HEM) surveys are being used for rapid mineral and ground water exploration, environmental investigations and also geological mapping in extensive areas. Despite this, one of the most important problems in using obtained data from the surveys is accurate ...  Read More

Investigation of HEM Forward Modeling Accuracy on Inverse Modeling

A.R. Arab-Amiri; A. Moradzadeh; D. Rajabi; N. Fathianpour; B. Siemon

Volume 20, Issue 77 , January 2010, , Pages 137-140

http://dx.doi.org/10.22071/gsj.2010.55362

Abstract
  Today Helicopter-borne electromagnetic (HEM) data survey play important role for high resolution and fast 3D mapping of resistivity structures within the vast area. The standard method of interpretation of these data is to inverse them frequently. As surveying system is not fixed during the survey, hence ...  Read More
