Abstract

In this study, the attenuation of 300 GHz signal propagating through a layer of leaves which can built upon the antenna radome is investigated. Three set of leaves (Lauren, Birch, Willow) are chosen in this measurement as likely obscurants which can stick to automotive radar radome and cause signal degradation. Transmissivity through uniform layer of the leaves with different water contents is measured. The water content is estimated in leaves drying gradually. The complex permittivity of the leaves with different water contents is estimated and these values are used to calculate the transmissivity through the uniform layer of leaves. Comparison of transmissivity in equivalent water layer with that of leaves having the same water content is made. Measured transmissivity through leaves is compared with that obtained by theoretical model.
