This paper is a review of manmade waves observed by the ionospheric satellite DEMETER. It concerns waves emitted by the ground-based VLF and ELF transmitters, by broadcasting stations, by the power line harmonic radiation, by industrial noise, and by active experiments. Examples are shown including, for the first time, the record of a wave coming from an ELF transmitter. These waves propagate upwards in the magnetosphere and they can be observed in the magnetically conjugated region of emission. Depending on their frequencies, they perturb the ionosphere and the particles in the radiation belts, and additional emissions are triggered.
Cet article constitue une revue des ondes d'origine humaine observées par le satellite ionosphérique Demeter. Cela concerne les ondes émises par les émetteurs TBF et EBF, par les stations de radio, par le rayonnement des lignes électriques et par les expériences actives. Des exemples sont présentés dont, pour la première fois, l'enregistrement d'une onde émise par un émetteur EBF. Ces ondes se propagent vers la magnétosphère, et elles peuvent être observées au point conjugué magnétique de leur région d'émission. Selon leurs fréquences, elles perturbent l'ionosphère et les particules dans les ceintures de radiation, et de nouvelles émissions sont déclenchées.
