| 摘要 |
The present invention provides an electromagnetic prober comprising a transmission antenna, a reception antenna, a reception signal processing section for generating an analytic signal on the basis of a detection signal of the reception antenna, and an analytic processing section for performing a predefined analytic process on the basis of the analytic signal, wherein the analytic processing section includes in-medium dielectric constant calculation means which divides the analytic signal into a plurality of time-based ranges and performs a predefined computation on average cycle periods in the respective time-based ranges of the analytic signal to calculate average dielectric constants in depth ranges of the medium corresponding to the respective time-based ranges. Thus, even an unskilled person can easily measure a dielectric constant at each depth level in the medium to determine a depth at which an object to be surveyed is present.
