Computer Simulation of Anomalies Created by an Array of Ferrous Objects in the Earth's Magnetic Field,

摘要

This report describes a FORTRAN IV computer simulation of a three-dimensional array of ferrous objects and its effect on the earth's magnetic field. The program output is a plot of the magnetic anomaly amplitude versus distance along a path similar to that recorded by a total field magnetometer passing over the array. The array size,object mass,direction of the earth's field and the altitude and direction of the path of the magnetometer are controlled by the user. One hundred and one computer words of storage are required for each pass. This study was done as part of a Range Clearance Technology task leading to the design of equipment for the detection of unexploded ordnance found on military ranges. (Author)
