Method for determining accurately coordinates of a GPR antenna relative to a fixed reference |
摘要 |
A method and apparatus for determining accurately a coordinate of a transmitting/receiving antenna pair relative to a predetermined reference position. The method includes placing a transmitting antenna in proximity to a reflective strip, transmitting a first signal from the transmitting antenna and detecting a reflection of the first signal received from the reflective strip at the receiving antenna located at a fixed distance from the transmitting antenna. The method further comprises determining a coordinate of the antennas relative to the reflective strip based on a parameter of the reflection. The method may further comprise detecting a second signal received by the receiving antenna from a conductive strip located proximate to the reflective strip, and determining a second coordinate of the antennas based at least on a time difference between transmitting the first signal from the transmitting antenna and receiving the second signal at the receiving antenna.
