The following thesis provides a detailed description of the design and development of magneto-resistive unexploded ordinance (UXO) sensor array to detect the perturbations in the Earth’s magnetic field due to the presence of buried ferrous objects. Over the years there has been a substantial development in the detection of unexploded ordinance. The objective of this research is to use the multiple axis sensors in the design to detect UXO. This thesis describes the theory of different magnetization techniques and the characteristics of Anisotropic Magneto-Resistive (AMR) sensors. The description of each hardware component employed in the system is given in detail. The softwares used for the data handling and processing is also addressed. The verification of a working design is achieved by acquiring baseline data set.
