Investigation of the influence of the type of the lightning diverter strip on the spectrum of electromagnetic interference on the antenna under the model of the nose radome of the aircraft by using an artificial thunderstorm cell

Abstract

The paper presents the results of physical modeling of the effect of solid and segmented lightning diverter strips on the spectrum of electromagnetic interference on the antenna under the model of the aircraft nose radome under the influence of an artificial thunderstorm cell. It is shown that the use of segmented lightning diverter strips leads to appearance of signals with frequencies up to a few gigahertz in the spectrum on the antenna. The relationship between the antenna signal spectrum and spectral characteristics of current pulses on the lightning diverter strip is established. The influence of discharges along the radome surface and those between the segments on the electromagnetic interference spectrum on the antenna under the radome has been revealed. Keywords: lightning, solid and segmented lightning diverter strips, model of aircraft nose radome, artificial thunderstorm cell, wavelet spectrum, discharge.
