IPhO2002 1 I. Ground-Penetrating Radar Ground-penetrating radar (GPR) is used to detect and locate underground objects near the surface by means of transmitting electromagnetic waves into the ground and receiving the waves reflected from those objects. The antenna and the detector are directly on the ground and they are located at the same point. A linearly polarized electromagnetic plane wave of angular frequency ϖ propagating in the z direction is represented by the following expression for its field: ( 29 z t cos e E E z 0 b w a - = - , (1) where E o is constant, a is the attenuation coefficient and b is the wave number expressed respectively as follows 2 / 1 2 / 1 2 2 2 1 1 2 - + = w e s me w a , 2 / 1 2 / 1 2 2 2 1 1 2 + + = w e s me w b (2) with m , e , and s denoting the magnetic permeability, the electrical permittivity, and the
