Design of a data acquisition system for passive detection of buried explosives

In this study; a system has been designed to detect buried explosives which contains ferromagnetic materials by means of magnetic anomalies caused by these explosives. In order to detect these materials, a passive measurement technique is used differently from conventional one. For this purpose, a sensor network having 32 nodes of TE100 fluxgate magnetic field sensors has been designed. This sensor network has been moved in a mechanism having cartesian motion capability, and data have been taken from 6 different test samples. Two-dimensional-gray scale images have been created for the obtained 32×25 size data.
