Paper Abstract

The paper presents experimental data on electromagnetic radiation propagation at a frequency of 5.2 GHz through pine needles at negative temperatures. Hysteresis of electromagnetic losses under a temperature cycling in the range from -10 to -30°С is revealed. Variations in the signal power at the same temperature and mean attenuation of 3 dB reach 1.6 dB. This effect should be taken into account under remote sensing of coniferous forests in winter.
