Identification of Subsurface Objects by Amplitude-Frequency Response Characteristics in the Microwave Range
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.
