✦ Synopsis
The fundamental characteristics of signals reflected from objects buried in the ground were measured with a CW radar system. In this measurement system, the reflected signals from buried objects are detected synchronously so that the measurement of amplitude and phase of the reflected signals is possible. From the results of measurement, it was found that the reflected power from buried objects is almost proportional to the minus fourth power of the equivalent distance and that the phase variation agrees almost with the result anticipated from Snell's law under a plane wave approximation. From these observations, it is found that the measurement of the reflected signals from buried objects is possible with a CW radar system, and that underground remote sensing also is possible.
