The aim of this work is to get far field radiation patterns for any radiating source from transient acquisition, in a large frequency range. An outdoor transient Ultra-Wideband near-field measurement base will be installed, a single time pulse radiated by the source will cover the desired spectrum, and the accurate determination of far field radiations will be accomplished by means of cylindrical waves' modal development. This method uses simplified test equipments, easy to be installed, and it reduces measurement costs.

Many studies were devoted to the analysis and the detection of electromagnetic attacks against critical electronic systems at the system or the component levels. Some attempts have been made to correlate effects scenarios with events logged by the kernel of the operating system (OS) of commercial-off-the-shelf computer running Windows. Due to the closed principle of the last OS, we decided to perform such an analysis on a computer running a Linux distribution in which a complete access to logs is available. It will be demonstrated that a computer running such an open OS allows detecting the perturbations induced by intentional electromagnetic interferences at different levels of the targeted computer.Index Terms-Electromagnetic compatibility (EMC), electromagnetic interference, software engineering, system analysis and design.
