Kanyou Nana kanyounana@hsu-hh.de S. Korte S. Dickmann H. Garbe F. Sabath Helmut-Schmidt-Universität/Universität der Bundeswehr Hamburg, Germany Leibniz-Universität Hannover, Germany Wehrwissenschaftliches Institut für Schutztechnologien, Munster, Germany The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their produced electromagnetic fields. The paper focuses on the coupling of UWB fields into electronic equipment and discusses possible modeling and measurement techniques to estimate such a threat for modern ships. An evaluation procedure for the determination of the induced voltage at the input of an electronic component is presented. This method is based on the computation of the internal electric field and the measurements on a test network, which is similar to the structure of the steering control cabling. It allows the estimation of the potential threat for the ship's electronic equipment due to the exposal to UWB emitting sources.
