Abstract
The resonant properties of dielectric subsurface objects in the microwave range are considered. The paper gives formulas and experimental results for the properties of some small-size (∅ ≈ 200 mm) dielectric objects in sand with a moisture content of 6% at depths up to 8 cm at frequencies of 270-620 MHz and for metal springs which can be part of these objects at frequencies of 900-1200 MHz. It is shown that the objects can be identified by their amplitude-frequency characteristics in the microwave range.
