A microwave radiometric study of buried karst topography
Kennedy J. M. ,
Abstract:
To prove the potential of microwave surveys in locating and mapping subsurface voids, a mobile laboratory was used to obtain in situ data. This unit is equipped with passive microwave radiometers operating at 13.4 GHz (2.22 cm), 37 GHz (8.1 mm), and 94 GHz (3.2 mm). An area near Cool, El Dorado County, California, is known to have well-developed subsurface karst and has been surveyed by the California Highway Department and the California Rock and Gravel Company. The microwave survey showed significant radiometric 'cold' anomalies associated with void-space beneath several tens of feet of soil cover. Detection was positive in almost all cases. Microwave systems may be used to greatly reduce surveying costs in the areas where caves have developed beneath cover
