摘要：
A method is described for use in a region which contains at least first and second in-ground cables, each of which cables includes an electrically conductive component such that, when the first cable is driven at a locating signal frequency to emit a locating signal in an electromagnetic form, the locating signal can be coupled to the second cable in a way which causes the second cable to generate a false locating signal in electromagnetic form. The locating signal is received along with the false locating signal as well as receiving a reference signal which contains the locating signal frequency impressed thereon. The locating signal is distinguished from the false locating signal based on the locating signal frequency as contained by the reference signal.
