Abstract
The invention relates to a full-polarized ground penetrating radar array antenna. A T-shaped, cross or rectangular array antenna is composed of three or even n numbered Vivaldi antennas, wherein the co-polarized Vivaldi antenna is perpendicular to the cross-polarized Vivaldi antenna, and the two adjacent Vivaldi antennas which are perpendicular to each other are connected by a hinge. The feed point of each Vivaldi antenna is provided with an electronic switch, the electronic switch is connected with a ground penetrating radar through a lead wire and a multi-port electromechanical coaxial switch, the Vivaldi antenna is a transmitting antenna if the feed point is connected to the transmitting end of the ground penetrating radar, and the Vivaldi antenna is a receiving antenna if the feed point is connected to the receiving end of the ground penetrating radar. By using the invention to carry out geological detection by means of the ground penetrating radar, both co-polarization information and cross polarization information can be simultaneously received. Thus, the array antenna can transmit and receive a group of orthogonal polarized waves. In practical situations, the invention can be subject to single-shot point or multi-shot point activation, thereby meeting different detection requirements.
