Abstract
An object detection system may be capable of sensing a buried object and providing an estimate of the object's depth. The object detection system may comprise a signal generator transmitting one or more signals. At least one of the signals may be directed toward the buried object and reflected off of the object back to the system. At least one of the signals may be transmitted along a variable length path. A correlator may then receive the signals and determine an offset between their arrival times at the correlator. The variable length path may then be adjusted over a range which includes a minimum offset indicating a distance to the object.
