Abstract	Radiation effects in the near-field diagnostics of weakly absorbing dielectrics are studied theoretically and experimentally. Calculations are performed on the basis of the developed theory of the near-field radar of a plane-layered medium, which is used for calculation of the complex impedance of a probe situated above the interface of a homogeneous medium and an inhomogeneous medium. It is found that the height dependence of the active part of impedance is characterized by “wave” spatial scale h $_{w}$, whereas the reactive part has quasistatic scale h $_{qs}$, where h $_{qs}$ ≪ h $_{w}$. It is revealed that the response of a near-field radar contains a parameter sensitive to the radiation fields of the probe. It is shown that recording of this parameter can substantially extend the sensing volume of near-field radar.
