Abstract : In near-subsurface imaging, the antenna constitutes an important part of the probing device. Unfortunately, during the data processing sequence, its radiation pattern is often neglected, inappropriately approximated, or accurately modeled, but with heavy procedure. In the present work, we propose an approach for accurately modeling the antenna behavior. The methodology was derived keeping in mind that it must remain simple to implement and that it should not require a complete description of the antenna geometry. Instead, a correctly balanced set of elementary sources, acquired through free-space transmission measurements, are introduced to mimic the antenna radiation characteristics. Comparisons with experimental fields acquired in controlled laboratory conditions show that this procedure allows a correct implementation of the antenna effect.
