A numerical investigation of UWB wave propagation inside a module of the International Space Station

A numerical investigation of the electromagnetic pollution produced inside a model of a module of the International Space Station (ISS) by a radar UWB is shown. In particular, the work investigates possible narrowband interference and the level of the background noise introduced by an UWB radar because these phenomena may decrease the QoS of existing wireless networks and apparatus. This study is part of the project “Non Invasive Monitoring by Ultra wide band Radar of Respiratory Activity of people inside a spatial environment” (NIMURRA) which refers to a feasibility study of a ultra wide band (UWB) radar applied to the breath activity monitoring of astronauts.
