Abstract

A concept of adaptive antenna for ground penetrating radar applications is presented. The adaptation is achieved with respect to the antenna footprint in the ground. The shape and size of the subsurface footprint of the antenna can be changed to improve detection and localization of buried targets. The adaptive antenna is based on a wire bow-tie structure since this structure makes it possible to switch on/off its wire elements in order to form a bow-tie antenna with certain flare angle. By adjusting the flare angle in this way, the shape and size of the subsurface footprint can be varied.
