Multi-frequency locating systems and methods

A buried object locator system, comprising:

• a buried object transmitter configured to:
• generate one or more output signals including a plurality of signal components at ones of a plurality of different output frequencies;
• a coupling apparatus for coupling the one or more output signals from the transmitter to a buried object in the ground to generate a buried object current;
• and
• a buried object receiver configured to:
• receive radiated signal components associated with the buried object current at a plurality of the different output frequencies;
• and
• determine, at the buried object locator, information associated with the buried object based on two or more of the radiated signal components.
