Detection of Buried Object By Electromagnetic Shock Waves Radiated Through Slotted Parallel Plate Transmission Lines

A method for detection of buried object by the transmission of electromagnetic (EM) shock waves is presented. The system has two parallel plate transmission lines inserted inside the ground. A transmitter is connected to one of the lines and a receiver is connected to another of the lines. Gaussian pulse is injected into one of the lines in which plate facing the unknown object is slotted. The pulse gradually leaks out. If the speed of propagation in the line in which the pulse is injected is faster than 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 lines. If any object is present between the two lines, it diffracts the shock wave. By comparing the signals with and without scattered by that object at the received port, the location of the object is determined.
