DETECTION AND DEFINITION OF SUBSURFACE VOID SPACES BY GROUND-BASED MICROWAVE RADIOMETERS
Results of an experimental program to detect and define subsurface voids using passive microwave radiometers is reported. A field measurements program was conducted at selected locations in Kansas. A mobile field laboratory was used to gather measurements using radiometers operating at wavelengths of .8-21cm. Data were also obtained concerning ground truth parameters of soil moisture, temperature and density. Sensed electromagnetic data were correlated with ground truth data to determine the effects of soil parameters on microwave and infrared signals. The analysis identified significant anomalies worthy of further investigation.
