Résumé

L’objet du présent article est l’analyse de la propagation d’impulsions électromagnétiques au-dessus d’un terrain pouvant présenter des irrégularités topographiques ou des inhomogénéités électriques. Pour ce type de terrain dont le profit est donné dans le plan vertical contenant l’émetteur et le récepteur, les auteurs adoptent un formalisme intégral qui fournit des solutions numériques. Des résultats expérimentaux, à savoir la composante verticale du champ électrique, provenant d’éclairs naturels ou déclenchés, sont présentés ainsi que les résultats issus d’une simulation théorique.

Abstract

This paper presents an analysis of the propagation of electromagnetic pulses over a ground which can be irregular or inhomogeneous. For this type of terrain the profile is given in a vertical plan containing the transmitter and the receiver, and an integral formalism supplying numerical solutions is used. The experimental results of the vertical component of the electric field, coming from natural or triggered lightnings are presented together with results of theoretical simulation.
