Self potential or spontaneous polarization method is based on the surface measurement of natural potentials resulting from electrochemical reactions in the subsurface.The self potential method ranks as the cheapest cheapest of surface surface geophysical geophysical methods methods in terms of equipment necessary and amongst the simplest to operate in the field.It ¿does not require electric currents to be injected into the ground as in the RESISTIVITY & IP methods methods.In the present book, several new approaches have been developed to interpret SP data caused by simple geological structures Prof. Dr. Mahfooz A.

One of the most important and tedious problem confronting the human safety is landmine detection. A reviews the detection techniques of APM using GPR and Em and describes particular situations where each technique is feasible is presented. We provide an analysis for fusion based detection and classification of APM. The GPR and EM data acquisition, signal processing also include a comparative study of these two sensors with respect to signal processing and target detection procedures. The strengths and weaknesses of each of the sensors based on data capturing efficiency, overcoming environmental difficulties and sensor technology. Finally, we emphasize that a geometrical feature based sensor fusion, combining GPR and EM for detection and classification of APM may be the most effective technique. Detection of landmines using recent developments by using dual sensor technology by combining EMI and ground penetrating radar (GPR) have enabled improved discrimination against small metal fragments to be demonstrated in a test landmine field.
