Magnetic Signature Analysis & Validation System

Abstract

The Magnetic Signature Analysis and Validation (MAGSAV) System is a mobile platform that is used to measure, record, and analyze the perturbations to the earth's ambient magnetic field caused by object such as armored vehicles. MAGSAV was developed in order to efficiently obtain magnetic flux density maps of armored vehicles. The field maps have a spatial extent of 24.75 m by 24.75 m in a given horizontal plane above ground level (AGL). A field map is composed of a grid, or matrix, of 99 cells by 99 cells. Each cell has a spatial extent of 0.25 m by 0.25 m and possesses a single magnetic flux density value, in units of mgauss, which represents the total static field at a point in space relative to the target. The target center is registered in the grid center. The field measurement process is conducted at tour heights AGL and then intermediate planes are obtained through interpolations. The resultant "magnetic field cube" provides a three-dimensional matrix of magnetic flux density values spatially registered to the target.
