Abstract

This paper investigates signal reduction due to contamination of low-THz radar radomes for outdoor applications. A measurement methodology is proposed to characterise the effect of different obscurants on electromagnetic wave propagation. This is achieved by measuring the ratio of two signals: one reflected from the reference target through the contaminated radome and another through the radome without the contaminant. The presence of water content in propagation media is the main cause of performance deterioration of sensors in rainy, snowy and foggy weather. Therefore, the reflectivity and transmissivity of water films on the radome has been measured and analysed at 150 and 300 GHz and measurement results are presented. The measured results are compared to a theoretical model and good agreement has been established. The results show strong correlation between signal reduction and uniform layer of water thickness.
