ABSTRACT: A penetrating microwave radar ground plane antenna system with separate arrays of transmission antenna elements and receiving antenna elements. The lengths of transmitting and receiving antenna elements are selected to enable the transmission of a nearly single-cycle pulse, the reduction of ringing between antenna elements, the reception of a signal significantly reduced in noise, and the penetration of materials having varying dielectric constants.
