Environmental Sensitivity of Large Stealth Longwave Antenna Systems

Abstract

This article presents an analysis of measurements collected during a six-month-long experimental deployment of a surface-placed horizontal magnetic loop antenna. The changes in the measured parameters of the loop are investigated in relation to the surrounding environment’s composition, temperature and water content. Basic functions describing these changes are formulated. The results are confronted with outcomes from similar experiments from previous years and different locations, showing good compliance. The developed functions and antenna system can be used for environmental monitoring of soil composition and humidity over large areas and volumes, helpful in, for example, flood awareness.
