A crossbore detection system. The system is located in a downhole tool proximate a drill bit. The system comprises circuitry sensitive to a subsurface environment and a sensor that detects changes in the circuitry. The sensor detects changes in the circuitry that indicates that the drill bit has struck an underground pipe. The sensor may detect a series of electromagnetic signals indicative of the strike or may detect changes to an impedance bridge at a capacitive sensor.

Horizontal directional drilling crossbore detector

An adaptive UWB radar front-end that can a) automatically tune the pulse width for target type and depth; b) automatically sweep specific area by controlling the timing (delay); and, c) for each steering direction, it can automatically adjusts the power distribution for improving radiation pattern and thus improving signal quality for clutter free imaging.

Method and apparatus for detecting buried objects

A method of surveying the condition of an underground enclosure including the steps of: (a) positioning at least one transmitter/receiver unit (including an antenna) within an underground, substantially nonconductive enclosure, such that a substantial air gap exists between the antenna and the inner wall of the enclosure; (b) transmitting an ultra wideband (UWB) signal toward at least a portion of the inner wall; and (c) processing the return signal in order to identify the interface between the soil and a region of conductivity different from the soil.
