GPR antenna pattern analysis for impulse excitation UWB transmitter on arbitrary distance

The GPR use to solve problems of demining with handle driving yields a extremely complex radar model because work at the boundaries between the near, intermediate and far antenna and target zones. In the paper UWB radiation is represented as a cascade of independent ages. The requirements on the antenna size and the excitation pulse length are defined. The model of antenna aperture is assumed to be a set of discrete Huygens sources, which provides a generalized description in all antenna zones.
