Spatial Water Content Measurement with Time-Domain Reflectometry

Keywords: time-domain reflectometry with spatial resolution, water content profile reconstruction

Time-domain reflectometry (TDR) is a well-known method for measuring moisture in materials. Standard waveform analysis only provides the average water content along the TDR sensor, while more sophisticated methods are required to resolve the spatial water content profile. A reconstruction algorithm has been developed which calculates water content profiles based on TDR reflection data. Several examples in lossless and lossy materials are presented.
