SYSTEM AND METHOD FOR GROUND PENETRATING RADAR COMMUNICATION USING ANTENNA CROSSTALK
First Claim
Patent Images
1. A method of communicating with ground penetrating radar, the method including the steps of:
- providing a transmitter and a detector each coupled to a tool configured to penetrate the ground;
communicating a ground-penetrating signal with the transmitter;
detecting crosstalk from the ground-penetrating signal with the detector; and
determining a position of at least one of the detector and the transmitter relative to the ground based on a characteristic of the crosstalk.
