Abstract

GPR data collection in the frequency range of 3 to 66 MHz has been performed by the U.S. Air Force Research Laboratory (AFRL). To process this data into images, the relative permittivity of the medium is a key parameter since it determines the propagation velocity through the medium. Image formation using phase information returned from buried scatterers can be improved by matching the processing to the environment in which radar measurements were taken. Considering the permittivity to be an unknown scalar parameter, several images can be formed as a function of the unknown parameter leading to a choice which maximizes the sensitivity and resolution of the resulting image. In this paper we extend upon this concept to include variations of the medium that are nonhomogeneous with respect to the physical locations of receiving sensors.
