Abstract

To investigate the possibilities of electronic steerign of an antenna footprint in the near field, an array-based GPR has been built. The antenna system of this GPR consists of a single transmit antenna and 6 receive ones. For the transmit antenna a Vivaldi antennas have been used as receive one. The antenna array has been optimized to provide high-resolution iamges of theshallow subsurface. Footprint steering has been implemented in the digital signal processing via true timedelay of the received signals. The performance of the radar has been investigated experimentally. Electrical scanning along the array has been achieved, and 2D localization of buried objects without mechanical scanning has been demonstrated.
