Abstract
A method for detection of underground anomalies including in a system of distributed antennas (), which are leaky transmission lines, disposed inboreholes () formed in a ground, a transmitter () being connected to one of the antennas (), and a receiver () being connected to another of the antennas (), injecting an electromagnetic pulse into one of the antennas (), wherein the pulse gradually leaks out, and wherein if a speed of propagation in the line in which the pulse is injected is faster than a speed of propagation in the ground, a shock wave is transmitted through the ground, called a transmitted signal, and received as a received signal at another of the antennas (), and wherein an underground anomaly diffracts the shock wave, resulting in a detectable disturbance in the received signal, and locating the anomaly as a function of a time delay of the disturbance relative to the transmitted signal.
