The Belgian project on humanitarian demining has been initiated by the Belgian Ministry of Defense and is supported by the Belgian Ministry of Defense and the Belgian State Secretariat for Development Aid. It is carried out in collaboration with laboratories of other Belgian universities, i.e. the ``Facultés universitaires Notre-Dame de la Paix'' (FUNDP), the ``Katholieke Universiteit Leuven'' (KUL), the ``Universiteit Gent'' (RUG), the ``Université catholique de Louvain'' (UCL), the ``Université de Liège'' (ULg), the ``Université libre de Bruxelles (ULB), the ``Universitaire Instelling Antwerpen'' (UIA) and the ``Vrije Universiteit Brussel'' (VUB), and it is coordinated by the Royal Military Academy (RMA) [

This paper is restricted on describing the efforts and their results for increasing the knowledge on sensors and on sensor/ground characteristics, for designing new sensors or tuning old ones and for processing the data produced by sensors. Furthermore, it considers the detection as a global process wherein the outputs of the sensors, considered as skilled specialists, are integrated in a fusion operation.
