Soil Moisture Content Inversion by Coupling AEA and ARMA [PDF]

open access: yesRadioengineering
This study aimed to explore the inversion method of soil moisture content by using numerical simulation and field detection. The researchers used the early signal amplitude envelope (AEA) method to directly invert soil moisture in the shallow part of the
