Amplitude, an important electromagnetic wave attribute, is considered as a useful parameter to describe the energy attenuation of electromagnetic wave. In this study, SIR-3000 Radar Equipment was employed to investigate the amplitude of electromagnetic wave in medium sandstone with different water content and depth. Results suggest that, with same water content, the decreasing of electromagnetic wave energy with increasing depth can be described by maximum peak amplitude, while, the decreasing of electromagnetic wave energy with increasing water content at certain depth can be described by average amplitude. In addition, energy of electromagnetic wave is negatively correlated to the dielectric constant because of the positive correlation between water content and dielectric constant. This study can provide significant information to the water measurement in aeration zone.
