Abstract
A subsurface detection system may be capable of sensing a buried feature and providing an estimate of the feature's depth. Such a subsurface detection system may comprise a signal generator transmitting at least one signal toward a buried feature and at least one signal along a plurality of various length paths. Each of a plurality of correlators may be associated with one of the various length paths and receive both a signal reflected by the feature and a signal transmitted along one of the various length paths. Each of the correlators may correspond to a distance to the buried feature. As the reflected signal reaches each correlator it may identify a time offset between the arrival of the reflected signal and the signal transmitted along one of the various length paths. By so doing, a distance to the buried feature may be estimated by detecting the correlator with the shortest time offset.
